Not Ranked
Andy,
I heard about the AFR heads and the numbers from the article you attached. Part of the story is missing though. Ford claims their 392 stroker in full crate form makes 430 HP. The motor Westech started with made 462 HP, so I wonder what other modifications were made to give it a 30+ HP bump beforehand.
I am leaning now towards the 392 stroker short block. Looks as though from the Westech article, the Comp Cams Xtreme Energy cam would work best with some high-flow parts like a Victor intake and a . I already have the Demon carb.
Can we build 500 HP and have streetability with reliability?
