My 400 is a basic .030 over stock shortblock with trw pistons. Heads are ported 16's with ram air IV valves. I don't know what they flow. Edelbrock rpm intake, holley 750 vac. sec. and hedman 1 3/4 headers. The cam is a cheater cam like the super stock guys run . It is 258-264 @ .050 with .516 lift. I love the cam. Turbo 350 trans with a 10 inch 3800-4000 stall and the rear gear is a 3:42. I kept the 3:42's so I could still cruise on the highway. I drive the car very often. I also didn't make any jet changes when I ran. Not bad for a 400, huh?
