Ok here is my next question to help me decide if I will get this thing.... Say that I want to pro street my 66 F100, well would a 460 and a built C6 be better and cheaper in the end to get the most HP 500 or so or would that be fine to get this 351C? What would you guys do? I actually can get a 460 and C6 that needs rebuilding for 250 bucks. A guy in my hot rod club here told me about it.
