Two things: F/I cam and 3.91 gears. Contemplating another cam since I'm likely to stay N/A for awhile. But 460-470 "corrected" rwhp off a Dynojet is about right for stock geared cam/exhaust LS3. I suppose if I did a LG G6X3 cam I'd be at the 500 level, but I'm not sure if I could live with it since I DD the car. I'm kinda searching for a more valvetrain friendly, but longer duration cam.
415 LSA block, Callies/Manley/Scat/Melling/Cloyes/ARP/Ferrea etc, Landspeed heads/Hi-Ram, Tick cam, nitrous, etc., built/tuned by me.
