Best 302 Mods?
hello. I have a 95 Ford F150 with a 302 v8 in it. Like any man out there, i'm craveing more power... I already have a cam, headers, throttle body spacer(useless), ram air intake, elec. fan to eleminate the fan off the block, 3inch exhast from the Ypipe back. I;m going to rebuild my motor because it seems alil weak. What can i all do to it to make it go good? I was thinking twin turbos for a mustang but i just would like to know my other options.... The turbo kit is $1200 approximately off ebay and I wasnt really wanting to spent much more... anyone got any ideas?!

A 302 by no means is a power house. The turbo setup is probably a little over kill. A stroker kit will jump those numbers up quite a bit.
Also a 3" exhaust a WAY to big for that engine! 2.5" MAX on an engine that size!
If your positive you want to do a rebuild do a compression check first, and see what the actuall oil pressure is with a mechanical guage. Heck your engine may be in perfect health. Then a twin turbo setup would go right in there. But its your $ so decide what you wanna do.
IMO a set of heads and a better torque converter would be more fun, less work, then hrs spent putting in turbos that will shorten the life of your engine.

well how muhc is that 331 stroker kit? the twin turbos are around $1200 for everything... I was thinkin running NO2 cause i sen how they hid it on a EFI mustang with a 5.0L... why is 3inch too big? is it robbing power? it sounds cool... the main reason why I want to re-do the motor is because when i checked the oil the otehr day, the oil was a white sludge, headgasket is going or gone!, i dumped the oil and its been good... The twin turbo set up would be almost a one-of-a-kind on a F150 4x4, never heard or seen it before. I kinda was going to go with Aluminum heads, higher cam, and a trickflow intake... but the stroker dose intrest me...

$546 for the extra, might as well go 347, same price.
If you get this deep into the motor, you should do a full rebuild and use forged pistons if you're going with laughing gas.....

well the NO2 was just a thought, i highly doubt i'll actually run it since i have a 4X4.
ok on the rpmmachine website, the hp rateings on the kits is off the crank right? and would that be still with like stoke efi intake and heads and stuff or no? Because if so then I think I'm goin to get the 331 stroker since it has up to 500hp, that would be good enough for me cause then fuel milage wouldnt drop to segnificant.
Oh I have another question.... Woul parts, like the intake and EFI set up/heads/headers from a 5.0L H.O. EFI in a mustang work on my regular 5.0L 302 EFI? Because you dont really find to much intakes around for the pickup 5.0's but alot for the stangs, working if they would work?

It is still going to set you back 2-3mpg. Yes the site is rating the HP to the assembly. You can use all the stock stuff. Just make sure you get a piston with enough dish to keep the compression ratio sane.
I dont know about the mustang stuff.
Most stroker kits also I might add, require some clearencing on the block. I.e. grinding a section to clear the rod bolts. One more thing.
If your going to stroke that motor, a stud girdle is almost a must! it keeps the main caps aligned and join the togethor as a unit to make it stonger. If your going to be looking for more than 400 hp then a lifter valley girdle is almost manditory. It keeps the block from cracking do to excessive flex and physical weakness's in the casting. Just my 2cents

ok.. The fuel milage isn't an issue to bad then. Ok what ampunt of hp would be comming off the block if I threw just a 331 stroker with stock intake/efi system, Trick flow twisted heads, shorty headers, and a medium cam?

IMO, A good rule of thumb is with a medium built engine. 1 HP per cube is close ratio. so with 331cubes stock induction I wold think around 325 at the crank maybe 335. Some where in there.

jt, thats pretty good numbers i think. the only problem is that how will the 331 stroker turn over in the cold temps, like -20'C with out wind in the middle of winter??? I think even like 320hp would be good enough for me with a lifted 4x4...

yeah I was told by amny to drop and 351 windsor in my truck. one guy told me to put a 351 block and use aluminum heads for a 302 on it and a cam and it would do good. I think the 351 would be nice but like JT said, the 302 is way cheaper to get good numebrs out of and is lighter (weight in my 4X4 is wahts slowin me down alot)
