On a $3k budget, a carb'd 351 or 351 stroker(373, 392, 408). You're not gonna get 400hp out of a 302 on $3k. I got about 370hp outta mine that's STREETABLE(the key if you drive your's every day) and did everything but the machining myself, and it cost me over $4k, but it's also built pretty stout. With a good EFI setup it may put out 400+hp(since I'm using a smaller carb/intake to keep it streetable, with EFI I can let it breathe better and still drive well). A carb'd 351 stroker could make 400hp rather easily for not a lot of money, but mileage will suck unless you have overdrive and good gearing

Are you talking about an EFI 351?

I actually do have to say i care about mileage because im only 16 . So i dont have that much money .

And Its a street car ,Im not a dragstrip Cali kid.

I think 400 is too much of a stretch for me , But who knows .

what kind of times am i looking at with this kinda of a set up , I was thinking about going 302 for the mileage since the 351 is alot bigger ,

But i dont want to be shown up on the streets all the time , So my guess is 351

I feel really ... dfihshw0awjigtaeioruth9aeruthe359uahe

About this , What would you recommend in my situation?

I was planning on going T-5 speed with OD . MAnual Transmission

Ding ding ding! 400hp doesn't mean diddly to most of us if it is all on the upper end and needs 1000+ rpm to hold an idle. I'd take a 300hp streetable motor any day over a 400hp that belongs on the track.

The 302 wheather EFI or carbed, mated with a T-5Z, and properly geared, (remember your car is about 500lb lighter than a fox body), will give you all you can handle on the street.

Default RE: 302 vs 351w vs EFI ?

So are you saying im in over my head ? And that i should stick to 300's ?

If anywhere im happy with anything past 350 hp maybe 370

And torque as long as im holding up about 380 or so .

that should make for a good A$$ hauler . shouldnt i be doing like 12's with that ?

I went off an ET calc , But 11.5 seems too fast for that much power so im saying around 12 is right ?

So the argument still stands ... 302 EFI ? 347 stroker ? 351?

I think you have a conflict of interest. If you want milage and decent hp grab a 302 if you want hp and raw strength go bigger. Mines a daily drive and the speed limits on most streets are 45 or lower and the freeway is 65. 302 is all I want.

Absolutely. A lot of people like the idea of a 400hp 302 that they can drive, and it seems fun at first. But after the novelty wears off in 3-4months, you start to get REALLY tired of driving a cantankerous beast. 400hp from a 302 can be done in a streetable package, but it's neither cheap nor easy. That's why cubes are good for budget street builds, it's easier to get streetable power.


As far as mileage in a 351...with a modest sized carb/intake combo and good heads and a roller cam, you can get 400hp and have decent mileage, especially with a 5spd and the right diff gear. But you also have to take into account chassis and suspension. Can your car handle 400hp? You need a good clutch, a decent trans, good u joints, a good diferential, preferably a locker or LSD of some sort, or you'll just fry 1 tire all the time, and suspension that'll hold it all without wheel hopping, breaking or otherwise just not putting the power down. There's more to power than just the engine
