Anyone have a proven aluminum headed, 500 hp, 440 six pack build?????????????

Agreed. The thought is stroke the 400 - 470/500, not sure, but I’m way out from doing this. Probably a 470, TF-240’s, in a 3800lbs B body-727/3.55’s.
I was think of a cam not larger than 242*@.050.

A Streetable street warrior is the goal, little to zero track time.
