i bet, 400ci and trueduals are the way to go. especially with the cam he's running.
for a simple reference, here is a breakdown.
single 3" - 28.27 in^2 OP
dual 2.5" - 39.27 in^2
single 4" - 50.27 in^2
dual 3" - 56.55 in^2 odarabla

Alright, i should have updated the old information. I decided to change the cat-back for a magnaflow setup, but i'm including an electronic cutout directly after the headers to help with airflow.
No, i'm not going to get another custom cam, as the one i just installed was specced for what i wanted.
At this point i'm just trying to squeeze everything out of it that i can. I just felt that the numbers it produced were below what it should have produced. Similiar setups have easily been 500+rwhp.

But I have Trick FLow 215cnc heads
Also remember that dyno #'s don't mean ****. My buddies 1999 SS with a 416ci LQ9 made 480rwhp and 513 torque to the wheels and ran a 10.26@133mph..

Well guess I will ask some obvious ?'s.
What is your static compression ratio on the 402??
What octane fuel are you running??
Do you have any additional build specs (tolerences, deck height?)
