Quote: Is the 5.7 cast crank and 6.1 forged? If yes, can the 6.1 drop right in to a 5.7? Also I hear that the eagle head bolted directly to a 04 5.7 will give you 12 to one compression, is it a dirrect bolt on or will pistons hit the head? [/ quote] Yes Yes Yes Yes No the piston will not hit the head.
