Just wondering what 347 stroker kit (forged) are best?? I wanna rebuild my GT-40 302 In my 97 explorer and then I plan on swapping a F-150 5 Speed into it.

I also am wondering what heads to use on it, I would like a high CR as I plan on running E-85 or premium if I can not find E-85.

What volume are the GT-40's??? I have read on other websights that 50cc heads will yeild 11:1 but what year engines came with these heads, and how much worse do they flow than my GT-40's I have??

Last question, what cam and rocker arms would work best with a 347 in a heavy ass explorer????
