351w into a 91gt

[Boosted93Notch]

i know it can be done but i need to know exactly what parts are needed to drop a 351w into my 91gt. i also would like to know what kinda power can the stock 351 crank and rods hold, plus what kinda power can the block itself withhold any help would be greatly apreciated

are ported gt40 irons to small of a head for a 351

 

[vristang]

a little bit....

but, whether or not they are a valid option will depend on your goals...

 

[Boosted93Notch]

i am only lookin at like 300-400hp. i have the heads already cause i was gonna redo a 320 but then was lokin at the price differences so im kinda stuck in the middle. could using ported gt 40s hurt anything. i was gonna use a cobra intake a ecam 1.7 rockers 70mm t body and ported gt40s on my 302 then possibly a 50-100 shot on top of that

Do the 351. Use the gt40's for now. Save up and buy a nice set of afr 205s later. I am doing the same build with 74 351 heads that will be ported. Won't get me my final goal at first but will still make a respectable runner in the mean time. Do the 351, you will be more happy in the end.

Oh, and use Jason's site, it will outline everything you need to do from top to bottom. Real good info there. Even has part #'s on some swap parts needed. (i think, if not let me know and I have them)

 

[vristang]

boosted,
The gt40's won't hurt anything...
(but the e-cam my cause some issues with idle and low rpm...)

Heck, I ran stock E7's on my 351w for a while...
I still liked driving it, and it was more fun than the 302 ever was... lol

one of the main reasons i was goin wit the ecam is so i can get it through emisions . what would be another good cam to use. i honestly would like to go custom

 

[squeak93]

Custom is best bet but if your having to deal with emissions, then you may want to look the laws up. I believe that you have the have the orig equipment the the car the motor came from was equiped with from the factory. Again, check your local laws before you sink an ton of money into something you can license.

yea i didnt even think about that man does that suck lol i wonder if a 351 can pass as a 302 with a sniffer test
