I'm about to call and order my new cam and lifters for my 383. It's a custom grind solid roller nitrous cam from Howard's. I'm getting the AFR 210cc aluminum heads from Jegs and they say that the springs can hold up to a .710 lift. I'm gonna make it a .640/.656 lift 295/315 duration. I'll post more pictures of my motor being put together when my parts start coming in. AFR heads, this cam, and the forged Scat rotating assembly, and hellfire rings.
