For full features; Go to 74 Chevelle or Nova
Alright, so i already have the pre-conceived notion that i will get a lot
of negative feed back on what i am about to ask help with. I have plans to
get a 1974 Chevelle or Nova, not SS. I am looking at taking it to something
people would probably make people look down on me. I don't want all the
macho big block engine due to gas prices, and plus i already have a 65
Mustang coupe that i have a 289 and 4sp for. Anyway, I'm looking at placing
a more modern 6cyl engine in it. For example: 1974 chevelle, take out a v6
of a 1994 chevy S10 with a 5 speed. I want to put the 6cyl and 5sp into the
Chevelle. What all would i need to go through with this? Don't be too harsh
lol.

At first I was going to ask why you would get negative feedback, but then i
saw your user name, and the scale started to tip toward BS. So then I
looked for your other posts, as to see if you were realy only 17, and look
what I found!
so let me get this straight. You want me to believe that you, a 17 YO
busboy that wants to get into tuning cars and couldn't afford a newer car 6
months ago, has a 65 mustang V8 and plans to get a 74 Chevelle or Nova. on
top of that you plan on getting a newer v6 and 5 spd and putting them in
it? Where did you get all the money from? And if there is any truth to all
of this, and you plan on pimping out a chevelle or nova, you can expect a
lot of negative feedback from me.
Maybe I am wrong, but something smells fishy.

My rents bought the car. They used money that they had been saving up to
get me a new car once i graduate. The motor only cost me 425 which i used
from my savings account, and that only left me with like a hundred dollars,
its been a long haul. And its not necessarily a newer 6cyl. Just one that i
can get from a junkyard for cheap. Nothing should be fishy from any of
this, i dont do or sell drugs, im clean. and im not really looking to trick
it out, just put the 6cyl and 5sp in, the nova's i see around my town have
a lot of surface rust on them, and i could possibly get for 200 at most.
The engine and tranny i can find for another 250.... 400 isnt that big of a
deal. When i posted that 6 months ago i was talking about going into JDM
cars. Which run easily around 2k if you go for an alright car. Domestic i
can find pretty cheap. It's cool with the negativity i expected there to be
some.

ok, i might believe you for now, just a couple questions
1. Which car did your parents buy?
2. Did you buy a motor, if yes, for what?
3. Do you realize that customizing is going to be your biggest expense?
Unless you have metal fabrication experience, there is no way it is going
to be cheep. Things like motor mounts and engine controls will have to be
custome made, unless you find a kit for your specific engine and car. A
cheep engine from a junk yard can also be a headache. Junk yards aren't
always careful when they pull an engine and may just blowtourch their way
through wires and such that may be in the way. Also keep in mind that newer
engines may have more complex electronics that you will need to figure out.
Depending on differences in weight distribusion, you may also need
suspension work.
4. Surface rust is called surface rust because it is visable, surface rust
is the least of your worries. structural rust can be a disaster waiting to
happen. Thoroughly inspect the underside of any car you are thinking of
buying.
5. any pix of the pony?
dvdrose18
My parents bought the mustang, I bought the 289 for it, it only had a stock
l6 in it, wanted more power. I do have pics, but the motor isnt in the car
yet.. i will try to get them on here in a bit.
Need4Speed90
Alright, so if i wanted to reduce the difficulty of the whole thing, would
an 84 S10 6cyl and 5sp be a better choice? Or do you have any suggestions
as to a 6 that i could get that i could add some power to? Any suggestions
at all?
Need4Speed90
v6 s10 naw. but i cant believe that im saying this. but a v8 s10 wit 5sp
would beat all
DARKtEAGLE
He wanted a V6 because of gas prices, which I can understand, not that I
would do the same, but I am an originalist.
My biggest concern would be if there is any kind of electronic emissions
control or fuel injection that would give you grief. I would think for ease
of instillation you would want a carbed engine, but then usually fuel
economy will suffer, and you have to worry about a high mileage engine.
Keep in mind that the engine bay on a truck is probably shorter than on a
car, so if you plan on using an engine-tranny setup whole, check where the
shifter and clutch will land. You don't want the shifter up against your
dash, and you might not want the weight of the engine too far back in the
engine bay.
Conclusion: It is probably more difficult and expensive than it sounds. You
probably should have left the I6 in the pony and gotten a different car to
put the V8 in.
It can be done, but would take a lot of planning and research.

So far the info given has been very practical..... instead of going back
over what has already been said. Here is how I would rationalize it. Think
of it as a math problem. Below are just a few numbers off the top of my
head someone (anyone feel free to correct the numbers as you see fit)
289 mustang - 12 MPG
V6 5sp combo in a Nova - 22 MPG
price of a gal of gas $3.25
price of the car plus parts for conversion $5000 (this is way low and not a
practical number but should prove my point)
Miles driven per week 500
so based on the above numbers.....
Mustang would use 42 gal/week - $136.50
Nova would use 23 gal/week - $74.75
for a difference of $61.75/week
5000 / 61.75 = 80 weeks..... over a 1 1/2 years just to break even.
So I'd say keep the mustang or if gas prices have really got you down the
idea of swapping the six back into the Stang may be the better option.

What about resale value?
chris_knows
Resale value is not a concern I normally factor in.... Resale of classic
cars is very subjective and can not be easily determined. In most cases
deviation from original is not necessarily a bad thing... and there is not
much you could do to a non-SS GM car to hurt resale.
Is this what you were getting at or am I off base?
corbett_auto
Yeah, that's exactly what I was thinking about.
chris_knows
Just to clarify I am not against the idea... I actually like it. But I
would not recommend it to anyone on a budget. I own a Gran Prix GTP with
the supercharged V6. I have always thought it would be cool to drop it into
a mid 60's Nova with modern suspension. But I was equally enjoy the same
car with the factory 6.
Sometimes you have to sit down a rationalize the idea behind a project. Do
you truly want a modern V6 for the fuel economy or just to be different? As
you can see doing it simply for the economics does not make sense....being
different has advantages too, but can end up eating deep into a budget.
corbett_auto
Yea, im goin for both, economics and difference. Thanks for all the imput
guys, i will sit down and try to figure something out.

As far as the mustang goes, putting a V8 in one that came with a 6 cyl,
there's more to look at than just the engine swap. Suspension was different
between the 6 and 8 cyl. mustangs. :2cents:
thefonz
Yea, we got the mustang all figured out, thats not what this posting was
about. But anyway.. is there a way for me to drop a factory 6 into the nova
and make it more fuel efficient?
Need4Speed90
What range of economy are you looking for? (MPG)...
Here are a few things you could do:
electronic ignition
get it properly tuned by someone who knows what they are doing
convert to manual trans
change rear gear ratio
change your driving habits--- ease into the throttle
I'm sure there are more....
Even in stock form I'd guess you could expect 15 - 25 MPG and after some
tweaking you may be able to reach numbers near 30MPG... The thing to
remember is acceleration and fuel economy are inversely proportional.
Adding FI would be an option too, but I was trying to keep the list on an
economic level.
corbett_auto
thank you, i was planning on putting a t5 in and taking the auto out. what
will the rear gear ratio do? and what is FI?
Need4Speed90
FI = Fuel Injection
thefonz
I was referring to the gearing in the rear end. By going to a numerically
lower number ring and pinion gear the engine will be turning less RPMs at
any given speed which can help fuel economy.... this will however cause it
to accelerate much slower. Before you decide on this route... do some
reading and ask enough questions to make an intelligent decision on what to
change to.
