i have asked for you're thoughts on what to power my 95 gt a couple of times, talked and discussed it with friends and every time i ask some one i just get more and more ideas. this is a really low budget deal and i will be buying some used parts "buddy owns a salvage yard" here is where i am stuck rebuilding a 302 bored 30 over? with a cobra intake gt 40 heads cai 24 lb/hr injectors bumped timing sct chip cai headers and dual exhaust with h pipe. benefits would be use 302 i have could buy used gt 40 heads and a cobra intake and throw in an e303 cam. so new parts would be chip headers cam and injectors. umm my other option would be to say the hell with all the computer and maf crap and rebuild my 351 put a high rise intake on it and slap a 4 brrl onto it now i could go with the gt 40 heads again but idk how good theses would be the rest of the engine save for cam would be stock so those heads should work decent? also what cam would work with that?i would need a differant fuel pump for the carb but i dont know what mods would work real well with the 351 option but it should give me more power n a little cheaper deal i think i could go with a dual 4 brrl set up n bump the timing up so idk theres my 2 plans oh n i have to do this by the time they decide to close the strip at the end of this summer "up here in wisconsin" because i got a bet with my buddy whose getting a 83 hatch "5.0" stock for now we are both in the same money boat so our mods if i stick to the 5.0 would probably be similar. n e ideas thanks if not i think ima start tearing down the 351 put a car on it try it n see what shell run. "i have most of the parts for it"

I'd go with the 351, but you don't need a high rise intake for the set up your talkiin about, i'd recommend a performer rpm airgap intake, it will make alot more midrange power, cause with the high rise you will have zero bottom end, if you plan on going carb'd youll have to switch out the fuel pump pickup in the tank, get one for a carb'd 84', and it'd be best if you run a mechanical fuel pump. I got a 351w in my 92' and its unbelievable how much of a power difference there is, like they say, there's no replacement for displacement!, you should have right at 385 horsepower with a setup like yours. good luck! and the gt40 heads will work fine, but they are going to hold you back over 5500rpm cause they don't breathe!, another reason a high rise intake wouldn't be the way to go.
