For full features; Go to Ford 4.6L. Good or Bad?
What do you guys think of the Ford 4.6 liter V8.
Personally I really think they dropped the ball on this motor. People
always say that these motors love boost, but come on really no High Comp
N/A motor love boost. People just say that because they dont make any power
N/A.
Sure Ive always hated mustangs cause im a GM and Mopar guy, but I try to
give everything a chance, and I almost bought a 2V 4.6 mustang that was
Supercharged until I found out the dang thing only made 335rwhp on 10
lbs.:orglaugh:
The 4 valves are slightly different though. I really like these motors.
They have a lot more potential but parts are also extremely expensive. The
only relatively affordably ported 4 Valve Ive found is from Patriot and Ive
heard of some quality issues with patriot. And the cams in a whole nother
thing. Most mustang guys Ive talked to all say the same wether it be 2Valve
or 4V, Cams in a Mod motor arent worth it. They say that for all the money
it costs and the HUGE pain in the ass it is to install them, they arent
worth the gain. Plus some of the 4V mach 1 guys I know are running top of
the line parts and only making around 380 rwhp on H/C/I.
Dont get me wrong the heads are great but the lack of cubes and expense
seems to cancel it out.
And on the 3V i think Ford should have just thrown some 4V heads on there
and charged a few grand more. Id actually want a new mustang if they had
like a 350hp 4V.
Whats your guys take on the Mod Motor, excluding the Terminator motors?
Enthusiast
Oh and on a side note I know two local guy very into racing their cars. One
is a 02 SS it has a Lid, Catback, Welds and a Stall. It runs 7.70s and is
daily driven.
The other is a 99-04 Mustang GT. It has EVERY BOLTON available for the car,
plus cams, nitrous, and welds, and it also runs a 7.70.
Seems like a lot of work to run with a near stock LS1.
Enthusiast
For one, I seriously hope you don't mean 1/4 mile for that SS.
Second, the 4.6L is a very good motor. I wouldn't let one example of a 4.6L
making only 335 rwhp with an unknown compressor size supercharger running
10psi on an unknown state of tune.
PontiacFan27
No the closest local track we have in an 8th mile, Kennendale.
Well its was a Procharger HU. I odnt know about the size but doesnt really
matter the car was runnin 10#s. Also the tune was done by a local shop
which, Ive seen a lot of strong running cars come out of.
After looking up into low boost street setups on the 2V 4.6 it seemed to be
about right. Ive seen S/C converts run door to door with only a bolt on LT1
Enthusiast
Are you thinking of buying a Stang now? Whatever happened to the ZR1?
I think if you're going to buy a 4.6 then add a supercharger, just get a
SC'd one out of a Lightning or Terminator. I don't know a ton about the
(originally) NA engines being good on boost, but from what I've seen with
the 03-04 Mustangs, those things can handle a lot of power on stock
internals.
giant016
I gave up on the ZR1 because aftermarket parts are so damn expensive and Im
just not one to leave well enough alone, I am lookin into a few LT4 C4s
though.
Enthusiast
You're basically comparing apples to oranges when you compare a factory
rated 260hp CONVERTIBLE with a factory rated 320hp hardtop...I guess you
didn't read any of the MM&FF articles comparing the GTO to the Mach 1 or
the top of the line fully optioned SS with the 03 Cobra.....For what it's
worth, a stock '99-'04 2v 4.6 can run in the 13's stone stock with a
5-speed, a good track, and good conditions.....the 4.6L in N/A form isn't a
torque monster like your beloved LT-1, LT-4, or LS series engines...it
takes a bit more finesse and driving skill to get them to where they should
be.
The new 3v is an excellent engine and responds amazingly to the slightest
of mods...you've got to try and look at what you're talking about in a much
less biased manner...I used to be a die-hard Chevy guy too, but even I saw
the light.

im getting either an 03 or 04 mach 1 auto for my first car i dont like the
setup of the whole shifting and gearbox on the manual mach 1's and im not
going thru the hassel of replacing it all. so im getting an automatic
transmission with either a vortech SC, or procharger SC i just need help
deciding i mean the vortech with intercooler would put me upto 484hp
420lbs/ft and the procharger would put me upto about 520hp but im asking
myself do i really need that much
jslow913
i'm a ford boy and i find myself constantly diappointed by the lack of a
302 in the lineup... it's not so much that the 4.6 is a bad motor, but it
sounds like shit and that is an all important part of any hot rod. when
your mustang sounds like it is going down the road with severe diarrhea, it
doesn't really matter how fast it is...
crazycarl88
Yah and a Stone stock LT1 from 93 can run in the 13s, under good conditions
also.
And an LS1 Can do it in the 12s Stone stock. Ever read GMHTP.
And about comparing a 260hp Convert to a 320hp hardtop. I was revering to 2
local street racers. One is a bolt on LT1 the other is a Supercharged and
bolt on 2V 4.6 convertible mustang, they run door to door.
Enthusiast
I have never seen or heard of a stock LT1 running in the 13's...my cousin
used to have a '97 Z28 with a CAI, full exhaust, and an LT4 chip...it ran
13.5's once at Atco on a 50* day...perfect conditions...everybody on the
net said it was a freak...nobody could understand why it was so
"fast"(considering he had less mods than most people who were in the
14's)...I've seen many modded lt-1's running in the low 14's. I've seen
LS1's with professional drivers go 13.3's in good conditions.
Apparently, people liked the mustang better...it's still in
production...what happened to your camaro/firebird platform...oh that's
right, into extinction.
Stock for stock, the LT-1's and LS-1's were faster than the 4.6
'Stangs...albeit not by much...especially when you consider the size gap
between the two engines.
Sick88Tbird
Okay first there is no such thing as an LT4 chip for these car, there is an
LT4 knock module but I dont know what your talking about.
Sounds like your cousin needs some driving lessons.
Second just cause you havent seen it doesnt mean it hasnt happened. Ive
seen a Bone STOCK Lt1 auto run a 13.64.
And usually a stock LT1 runs about a 14 flat at 100 or 99 mph. So I dont
know who you were talking to on the net, because this is common knowledge
on LS1tech and LS1LT1
If you go back and read GMHTP (GM High Tech Performance) they took a BONE
STOCK (didnt even change tire pressure) 35th Ann SS and ran a 12.95 or
12.97.
Definetly never heard of a 2V mustang doin that.
Oh just like a ford guy, revert to the "well the mustang is still being
made" arguement. Yah people liked yours more and I dont really care, people
like civic alot to and it still means they are slow.
And STock for Stock the LT1 and LS1s were MUCH faster than the 4.6s.
And once again dont bitch about our motor being bigger.
And now that I think about it. There are alot of people putting LS1s and GM
engines in mustangs see LS1mustangs.com but Ive never seen someone put a
4.6 into a car originaly equipped with a ls1 or lt1. Wonder Why?
Enthusiast
It was the LT4 knock module...my cousin always used to call it a chip and
so did I. And, he also didn't need any driving lessons...it was an
auto...I taught him how to launch it and he pulled nice 60's everytime.
I think you need to post up a link to that article from GM high tech
performance.
And no, the mustang/camaro did not have a big performance gap between them
as you would imply. I guess all comparisons will now have to be made
between the '03/'04 Cobra and your LS1's...you can't cry foul about that if
I can't cry foul about the diffence in displacement.
For what it's worth, a civic is no where near in the same class as any
performance vehicle...so that's completely irrelevant to this
situation...even if only being used as an example. Face it man, GM was
late to the dance and early to leave.
Sick88Tbird
Well this is from a different article but Im still looking for the 35th SS
article.
Oh and it came from here
http://www.gmhightechperformance.com/features/0211gmhtp_2001_chevrolet_cama
ro_ss_feature/index.html
Enthusiast
And just so you know the 99s werent even the best performing LS1, they were
still sporting the LS1 intake (not the LS6 as 2000 and up were) also the
99s mayb have still had the heavier metal gas tank.
Lets see a stock N/A 4.6 do that.
Enthusiast
For what it's worth, Evan Smith is a professional driver who can make
anything run faster than anybody else. I NEVER said that a stock 2v 4.6
could do that...but then again there was only a few professional drivers
running those uber-high 12's in perfect conditions. I live 15 minutes from
Atco raceway and am there quite often...I have yet to see ANY stock LS1 run
a time like that...neither have any of my friends who are also at the track
frequently.
With average drivers in both vehicles, they are very close. As a matter of
fact, I've seen LS1 powered 6-speed T/A's run 12.60 once...he had slicks
and full exhaust and God knows what else...the rest of the night he ran in
the low 13's...it was a 60* night and there were no traction issues. Some
of these magazines receive "ringers" from the factory...ringers meaning,
cars that run faster than the production models.
I believe it was Justin Burcham, owner of JPC, who ran a "pre-production"
Mach 1 to 12.90's. The production models ran close but 13.10's was about
as good as it got. Anybody can run anything and claim it to be "stock",
that's my point here. And we're not even on topic anymore...I think you
really wanted to start a debate instead of actually receive information
about the 4.6. A centrifugally supercharged 2v 4.6 should make more than
335rwhp, unless it's completely stock, untuned, and equipped with an
automatic trans...so something was wrong with that combo.
Don't let one car, with a less than optimum tune/setup, turn you
away...they are quick cars and very fun to drive...and speed parts are
cheaper than they are for GM's...not to mention easier to work on.
Sick88Tbird
Uhm no I was hoping omeone could change my mind or tell me something I
didnt know but I highly doubt parts are cheaper. You ever cammed a 4.6.
Trust me it expensive a pain in the ass and definetly not worth it. Ever
cammed a SBC? Easy as Pie.
Ever put longtube headers on a SN95-2 Complete pain in the ass. Why do you
think most mach 1 guys dont go LT, because its a complete pain in the ass.
They just justofy it by saing the stock manifolds are good to 600hp and LTs
arent much better than Shorties, which is complete BS.
Man down here in texas we must have better air or something cause youve got
some slow guys up there. My first time ever at the track with only Gears,
CAI, and LTS. No tune and the car ran like shit. Plus I had a tranny
shittin out. I managed a 13.3. FIRST TIME EVER in this car.
There is a guy on tech who put his LT1 into the 12s with just headers, CAI,
and a tune ONLY. his name is urbanhunter44. Look him up.
Enthusiast
I'm with you overall, but for some reason most of the stock 12 second
F-bodies I've heard of are 98-00s. IIRC the cam is slighty different, even
though the 00-02s regularly dyno higher.
giant016
That reminds me of an interesting conversation.
Whats your views on the bigger is better (with cams) mindet everyone moddin
an LS1 has lately.
On a stock cube car stay under a 230 230 duration is usually my rule of
thumb, maybe slightly bigger.
The smaller cams usually dyno less, but Ive seen alot of Trex guys get
taken down by more mild cams.
Plus a smaller cam with lots of mid range would be much better for roll
racing, conidering shorter gears wouldnt be required.
Enthusiast
I think it's just like the giant single-turbo Supra guys that have 1000+hp
but still run crappy ETs at the track for their HP. They want to be able
to say they have X amount of HP, even if it means sacrificing a nice torque
curve. You're average non-car person will be more impressed if you tell
them that your car has 500HP versus telling them your car runs 9s in the
1/4.
I don't know much about cam sizes as don't have the money to do the job
right (new rear, built up tranny, dyno tune, and might as well throw on
some heads) and can't really give you my rule of thumb. I'm just saying
I'd go for whatever gives the fastest ETs but can be street driven
practicaly.
giant016
A 4.6, whether it's a 2v or 4v, can still make big power on stock cams...no
sense in camming one(especially a 4v) until your eclipsing the 400rwhp
mark. As for the header install, no it's not that bad...raise the engine,
pull the steering shaft and you're in business...most people think you have
to drop the K-member, but you don't.
The stock manifolds are not good to 600hp...you are correct in that.
As far as cam duration, LSA's, and lift number...that will all depend on
the engine combo. You can have two cams, one with more duration, one with
more lift and they will operate equally in a specific rpm range. One thing
I know for a fact is that LS1/LS6 cars run hard with a cam.
Oh, I almost forgot...we have to compare the factory supercharged '03/'04
Cobra's to your LS1...can your stone stock LS1's run 12.60's? I didn't
think so. Are you aware of the roll-bar requirement dropping from 11.99 to
11.49? That happened shortly after the '03 Cobra hit the streets...a
pulley/tune/gears and you had a low 12/high 11 second daily driver.
Sick88Tbird
An LSx sure can do 12.60 bone stock ever heard of a Vette. You want to jump
up a notch then I will to. And if you read carefully in the first post I
said excluding the terminator motor.
It may have been cosworth that said turbochargers (boost) were made for
people who cant build engines.
I was refering to a stock cube stock headed LS1 car. Much over 230/230 you
make more HP but alot of times the giant cammed guys are being outran by
more mild cam guys. Some of the mild cam cars are in the 11s.
I know a bunch of Trex cars that dyno like 440rwhp CAM only and cant ET
worth a damn.
Enthusiast
All 4.6/5.4 engines regardless of number of cams are "mod" motors.
The Eaton supercharger makes up the deficit in cubic inches, that's all.
This is what I was trying to explain to you earlier in the thread...you are
comparing apples to oranges when you discuss the power
production/performance differences in these cars...they do not match up
equally...yet you continue to argue the fact...or course, you're GM's have
a power advantage over the little N/A 2v 4.6....but when the power swings
the other way you want nothing to do with it?
Go figure!
Sick88Tbird
Sorry that wa supposed to say terminator motor, and the first pot does say
that.
And I want refering to the Terminator motor cause I know it has great
potential straight fromt he factory cause it comes with a motor prepped for
boost and a power adder, most cars like that do have good potential.

Enthusiast
And for your 'Vettes, we have our GT500's...and for your Z06's, we have our
550hp GT's....Game, Set, and Match...Ford wins.
Back to the topic, the 4.6 is a very good engine, especially in terms of
durability/longevity...I've seen them run over 250k miles with oil changes
done every 15k miles, at best...and still perform well.
Sick88Tbird
Ford..of course its good..its famous for its high quality performance..it
can have better performance if upgraded with an Iceman Performance Part
(http://www.speedyperformanceparts.com/iceman_p.html)..this cools up the
engine, causing it to run in a very fair performance...
kurt
Haha well dont forget the GT barely outperforms the Z06 for twice as much.
And for your GT we have our soon to be released ~650HP Z07 or BlueDevil or
Corvette SS, Which will be FI, so it will have a great aftermarket and
power potential.
Game, Set, Match. GM Wins.
Enthusiast
Have any of those vehicles been released yet? No, so GM doesn't win. The
Ford GT runs low-11's on street tires and handles like it's on rails, the
Z06 doesn't outperform in any fashion. Sorry buddy, sometimes you have to
face the facts. Good job on trolling though.
Sick88Tbird
Oh I forgot to mention but your 500 hp gt500 wont outrun the base model 400
vette.
GT500s are over 4K lbs hahaahahah Way to go ford
Okay so lets say ford has it for now what are you gonna do when the new top
of the line vette comes out. Admit defeat, because its inevitable, it has
been approved for producion and it will be out.
Oh and I guess youve driven a GT before huh, you would know just how it
handles. Ive seen a bone stock Z06 with nothing but DRs run low 11s to. The
GT has a good traction advantage being mid engine, help the Z0 out a tuny
bit in the traction department and all the sudden they run very much alike.
Enthusiast
Just so you know octane magazine reported a 7:42 lap time for the GT at the
Ring. I do believe everyone was blown away when it ran a 7:29. Ill try and
find were I read about it. But these cars are much more equal than you
think here are lap times for each one at different tracks
GT Corvette
Z06
Top Gear Track 1:21.9 1:22.4
GingerMan Raceway 1:32.45 1:32.75
Hockenheim Shorttrack 1:14.1 1:11.5
Vairano testtrack 1:19.810 1:19.5
Oschersleben 1:42.84 1:40.3
Daimler-Chrysler Proving Ground 1:19.6 1:15.4
Virginia International Raceway 3:00.7 2:58.2
Also power to weight ratio is damn near identical on these cars on .01
seperates them.
Enthusiast
Reviewing the Hockenheim shorttrack results leads me to believe that the Z0
may actually handle better, as on the short track, as place were power has
less of a chance to shine, and grip and other handling characterists are
more valued the Z06 actually lapped almost 3 full seconds faster than your
beloved GT.
Enthusiast
And did they have the exact same drivers in each car for every
comparison...I'm certain they didn't. What I've been trying to say this
whole goddamn thread is that none of this is relavant...
You asked if the 4.6 was a good motor and the first response you got, you
started arguing...WTF? That's called trolling, you didn't care what the
response was...
If you have to ask if a "4.6 is a good motor" then you obviously aren't
that well rooted in the automotive world and apparently not much of an
"Enthusiast". And how many times did I say the LT-1 and LS-1's were faster
than a 2v 4.6...enough to not be having a debate over it.
Good day to you jackass.
Sick88Tbird
Sorry you got your panties in a wad. I didnt even want it to turn into this
but you had to go there.
I was hopin some people could show me some hard running N/A 4.6s especially
the 3 or 4 valves, but nobody did.
I wanted facts and different mods. Im not even that big into mustangs, hell
I was about to buy a mach 1 and I still only even know of two head porters
for the 4V motors. Im sure there are a ton more.
I was hopin someone could show me some built strong running na 4.6s and
prove me wrong, but no.
From personal experience I hate this motor, but Im not against changing my
mind. I used to hate the LSj also until I saw some strong running ones.
260whp from a few mods is pretty good for a 4 banger.
Enthusiast
...and for our Mustang you have your...nothing. Game, set, and STFU.
Camaro is dead.
The Corvette had a significant price disadvantage against the
Terminator...how do they compare?
I took my Fox to the track, guess what I ran?
What
Your NA argument is just as silly as import's hp/L. With a size
disadvantage, the 4.6 needs a power adder to be fast and remain civil. I
do know NA 4.6s running 11s though.
What
Ahh the classic, well the camaro is dead arguement. Dont forget its coming
back and as always it will be faster than the mustang.
Who cares if its dead its still faster than the brand new 05 Mustang GT.
Civics are still here, and that makes them......SLOW.
The new LS2 vs GT500. Well most GT500s are going for over the price of a C6
and the C6 will easily out run them. The Gt500s are just too heavy.
There you go Id like the here about the N/A 4.6s in the 11s
Oh and what'd you run.
Enthusiast
There are 50-state legal '99 and '01 4v cobras running in the high-11's
that are docile enough to be daily drivers...I have one in one of my MM&FF
mags, I'll have to look it up for ya. By the way...what GM motor has
4-bolt mains and is crossbolted on top of it all and can handle 1000+ hp on
the stock short block? oh that's right, not a damn one.
The "bolt-on" camaro that you said ran 7.70's in the eighth mile...what was
his trap speed and 60' times? I believe this to be horse-crap, I need some
more info please.
Stock GT500's run 12.20's at high altitude in the summer heat on stock
tires, with the traction control turned off, it'll still belt out
12.50-12.60's with it on...LS2 'Vette won't do that...not without going
into the PCM with a tuner.
Please supply me with more into on that 7.70 eighth mile pass, as well as
mods done.
-Don
Sick88Tbird
If those 50 state legal cobras are Boosted than I dont care, You can make
anything fast with boost, if not Id love to hear about them
About the bolt on camaro its an 01 SS. It has Welds a Stall, Gears, A lid
and exhaust, and he was running 7.70s. The car I do believe is faster now
cause I know hes been sprayin it and it may have a cam now, havent talked
to him in a while.
Here is his profile for tech

Post 24 is da best
About being able to handle 1K hp try the LS7. Ive seen a stock shortblock
one with twin turbos makes it to 1200+rwhp, seems as the thread has been
cleaned from tech though.
Also all the LS1s have 6 bolt mains.
And about the crossbolted maines or splayed mains, thats common in LT1s
almost everybody that builds an LT1 has 4 bolt splayed mains on. I was
gonna have it done when I was building one. 300 dollars at my machine shop.
Enthusiast
The 11 sec daily driver cobra's I was telling you about are NATURALLY
ASPIRATED!
You posted the same profile twice...7.70's would equate to high 10's or low
11's in the quarter...he's not running 7.70's with those few mods...even
with 4.56's and a real loose convertor...that time is either with spray or
it's BS.
Looks like you have no proof about stock block LS7's taking that much
power, so it's irrelevant. I know 4-bolt mains with the outter bolts being
splayed was used at GM but they don't cross-bolt the mains like Ford does.
Sick88Tbird
Well you dont have to believe it but its true, and there are alot of guys
who will tell you the same. It has 4:10 gears and a 4400rpm converter. He
drags alot of people you wouldnt think he should. Join tech and ask about
him. He has a ton of videos on there.
Most guys say the same thing about him when they first here.
And the second link I was tryin to post was a thread he started abotu mokin
a KB cobra and then all the mustang guys go there panties in a wad.
Apparently they troll the racing section so when anyone comes out and says
they beat a mustang they all jump you and then make excuses cause they are
slow.
Looks like you have no proof the terminator motors are hangin on at 1K hp.
Ive seen a few last at 800 but Ive seen a lot pop at 600.

No comment on the LS1s?
I was at a local mustang shop USA motorsports gettin the car dynoed and a
TT terminator showed up and he said the motors were shit and his let go at
like 650rwhp, so he built a stronger one and is runnin a prototype TT kit.
He runs on low boost and makes 700rwhp but the shop turned it up to dyno it
and has dyno graphs of it at like 890rwhp.
Enthusiast
Oh and I have a quote for you fromt he owner of that mustang shop,
concerning the power potential of the 4.6s N/A.
"you cant make chicken salad with chicken shit"
Haha from a mustang guys mouth
I got another good one from him, a 3000gt with hail damage showed up and he
goes DAMN looks like a fat girls ass.:clap:
Enthusiast
If he can't make a 2v 4.6 run...he should close shop immediately...it's not
hard or expensive to build a 490-550rwhp 2v.
Sick88Tbird
N/A are you crazy.
And even the guys on the mustang forums will tell you 500rwhp rfeliably is
expensive and hard and requires alot of boost.
Still dont believe me about the 7.70s and someone said he had got it down
to a 7.40 though, dont know if it was on the pray on the 7.40 or not though
Enthusiast
I wasn't talking about building a N/A 500hp 2v...I was talking about a
turbo/centrifugal....even KB's on a 2v will get up near 500rwhp with gobs
of tire shredding low end grunt.
Sick88Tbird
Well 500hp on a 2V requires a build motor, not cheap or easy.
NO comment on the Z runnin 7.70s or all the other bolt on, full weight LS1s
running 11s
Enthusiast
No, 500hp on a 2v does NOT require a built motor, it requires a
supercharger or turbo if that's your thing, around 10-12lbs of boots, full
length headers, off-road h or x pipe, minimum of 42lb/hr injectors,
aftermarket MAF, and preferably cams along with a GOOD tune...that's not a
"built motor".
NO, I don't have any comments on the Z running 7.70's...we don't have
anything like that rolling around my way...just like they don't have any
silly fast cobra's down his way.

I wa just reading up on a 499rwhp 2V, with full bolt on and a turbo.
It was built by a very rebuiltable mod motor builder. And even on a great
tune the Shop owner said it was just a matter of time before it popped and
the owner was aware and said hell I just wanted to do the top before the
bottom. After talking to him he doesnt think it will lat long at all
either, hes prepared for a stronger bottom end soon.
There was a post about it on Mustangforums.com

That's probably one of the few mustang oriented forums that I'm not on...a
stock 4.6 2v will handle that power fine, as long as it's not abused...at
that power level, the survival of the engine depends on the driver. I
personally know a guy with 518rwhp on his '02 GT with an intercooled
pro-charger, full exhaust and cams and a bullit intake...he's had the car
set up that way for 2yrs now...he races it regularly and drives it every
weekend...he's got a very conservative tune on it and doesn't race every
honda civic when he's on the streets.
It's when you've got the car running against an aerodynamic wall through
5th gear when a-holes lose a motor and then wonder what happened. Also,
too much timing in the tune up will cause you to lose a motor. Shops don't
like building 500rwhp 2v engines for customers because most people will
absolutely abuse that power.
But looking over that guys car, his times are impressive for his small
parts list...however, how long would you want to drive a car without
overdrive and 4.10 gears?
Also, I came across an '03 Cobra that's had a 4R70W slid in place of the
factory T-56 trans and he's got a 4800 stall convertor, a KB blower and
exhaust...runs 10.60's in the quarter. With 3.73 gears and overdrive it's
a highway friendly car too.

The car should still have overdrive though, its a 4l60E, And after talkin
to him and seein it run I am seriously considering building a car much like
his even though I am a serious manual proponent. Automatic are just so much
easier on the rear.
I do love cobras but it seems they are developing supra syndrome. Very few
of them make good numbers and still run good ETs.
LIke the old saying, "How are a 400 HP supra and 800 HP Supra alike? They
both run 12s"
Dont get me wrong there are some that can still make a stron pass down the
strip, but there are so many more that make great numbers and cant do
anything but a 60 or higher roll.
Enthusiast
I thought I read somewhere that he had a turbo-400 in that car...maybe it
was someone else's. If you're a chevy guy and want to go quick, I'd say go
for it.
A lot of cobra's do have the supra syndrome...the IRS in that car is known
for not planting well and rowing a 6-speed in a potentially 10-sec car is
not a task many can do well...lol. But, with a live axle and an automatic
they will fly...but not too many people are doing that...a lot of guys just
want a big power number....friggin mustang guys...lol.
The powdered metal connecting rods in the 2v are the main cause for concern
when you get up towards the 500hp mark...I just read an article, with a '98
GT that had CNC ported heads, cams and a 2.2L KB running 10lbs, it made
601hp...the stock short block is probably not long for this world but it
did make plenty of dyno runs on it's journey from 500hp to the 600hp
mark.
I also found an article from MM&FF...stock 2v with a centrifugal that made
350hp with a full stock exhaust, so if that's what you were talking about
at the beginning of the thread, then I could agree with that.
The later f-body's have an extremely well set-up rear suspension too.
Thumbs up to GM on that.

Yah I really like the etup on the F-bodys I just wish it cam with a 9" or
12 Boltor Dana 60, hell Id take a 8.8".
But no stick u with the 10 bolt that you can break on the street with
street tires.
Enthusiast
I think a Dana 60 in an F-body would be a little excessive...lol. The 8.8
can stand for some upgrades too when you start looking at shooting for
11's.
Sick88Tbird
Amen to that. Pretty much the #1 reason I won't be doing serious upgrades
untill I'm done with school.
giant016
Well we call the T56 the rear killer.
And the Dana S60 is the newest rear for our cars. They are also currently
the cheapest and some say they are just as strong if not stronger than the
9".
Its what I plan on doing if I ever do a rear.
Enthusiast
LOL, yeah powershifting a T56 will send a rear to an early grave...good ol'
chevy guys turning to Ford or Mopar for driveline solutions...lol.
Sick88Tbird
I considered doin a 14 bolt but never really tried.
Enthusiast
I ran w/them when I had just bolt ons no nitrous....w/nitrous I would have
killed him.
It seems to me that your just hardcore bowtie. I agree with you on the 4v
I wish I had it.
I can't wait until the new camaros come out to see what they actually have
hp wise I no what they claim they are going to have but how many times will
that change when they come out.....just like the day they were to come out
that has changed too in the past...they look sharp no doubt about it.
Fizze06
Man theyll have the LS3 and it will probably be rated like 30 or 40 hp hy
of the vette but we all know it will be the same dang motor.
About me being die hard bowtie, not really man. I joke about hating for but
I really actually liek ford traditional V8s but not the mod motor.
I found out why the 2V are such dogs stock they flow like 160cfm on the
intake side, that is PATHETIC and ported they are gettin liek 230 BLAH.
The 3valves arent all bad though as ported one are flowing a little lower
than ported LT1s around 270 cfm, that could make decent power.
Enthusiast
I dunno, mixed feelings. They are supposedly very reliable. My main beef is
that they aren't compact and thus not very good for motor swaping. I wish
Ford had done another 3-4 years on the 5.0. They could have taken it up
there. If they had switched over to alluminum block or 4/6 bolt mains with
GT40 heads as standard, they could of had a real contender on their hands.
Instead, they didn't, which was the wrong move performance wise imho, but
maybe it was good as far as reliability and such.
Will be interesting to see what they pop out with in 08 when the
"Boss/Hurrican" V8 comes out.

I don't think ford even wanted to consider building a 300-350hp 5.0...thin
wall casting block...not the best for reliability...though I've seen stock
5.0 blocks handle 550-650rwhp...they won't do it for long. It would have
been nice, but oh well.
Sick88Tbird
Well they have 3/8" between each bore which really isn't that bad. The
issue is that the block cracks at around 500hp for the late model HO
blocks. The early model versions hold more, same if you have a girdle and
balance the vibrations out well.
