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.

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?

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.

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.

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

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.

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.

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.

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.

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.

The 2011 Mustang GT will have 400hp, right? It should be on sale in a year or less.

Hello Im another texas boy and would love to have the ability to run a 12 second pass n/a up here on the high plains.. I live in lubbock and own 2 stangs one a 95 cobra with an old paxton blower and a 2004 gt with a p1sc supercharger... my buddies 1996 ta bone stock runs 14.4 at 96 , and his brothers 2002 ta ran a 13.9 at 101 bone stock...just as a reference I bought this car in dec of 2007 and had it modded probably within 6 months or so.. I took it to the track and bone stock with a 2.2 60' it did 14.86 at 95mph I had a set of slicks and bolted them on and it did a 14.2 at 95.45 with a 1.9 60' bone stock 70,000 miles and in 5000' air ... which is a 13.2 in good sea level air... i managed to get the boltons on the car almost all of them.. 70mm tb plenum 3.73 gears upper and lower control arms , CAI , and a tune and it dynoed 258hp and 304lb ft of torque... I took it to the track and borrowed some 16"et streets and cut a 1.76 60' and got a 13.67 at 95.63 with a 20 mph head wind and 5500' air... I think corrected thats a 12.70 at sea level .. on a bolt on car... I know of one in ennis texas that did a 12.1 with similar mods and cams , man I would kill for that air... you can make them quick with just simple things even without boost, I have yet to dyno my car with the procharger as i learned that dyno numbers dont mean jack shit at the track, and ours has been closed for a year now...Im hoping for a 12.50 or so in decent air like 4500' for us is decent...lol
