Advice on H/C Set Up for Vette Looking for advice (lots of heads / cam folks on this forum) on the following setup I am getting ready to install -
AFR 205 heads; Crane Cam 112 LSA, 224/224 Duration, 580/580 Lift; Crane 1.78 - 1.7 roller rocker kit; FAST LSX 90MM Intake; Shane 90MM Throttle Body; 85MM MAF; under drive pulley and blueprinted oil pump.
I have a 2001 Corvette convertible 6-speed manual 3:42 rear end with SLP long tube headers, Corsa Indy Cat Back exhaust and X pipe, "Y" K&N air snorkle. MTI dyno-tune at 334 RWHP and 337 RWTQ.
Trying to get up to around 425 RWHP and maybe 400 RWTQ while retaining street manners and driveability. This car is set up for autoX and occaissional hot *******, no serious racing.
Wanted to see if some of you hardcore H/C folks have any suggestions or other comments regarding the above before I break the car down and put it all together (I turn my own wrenches).
Thanks for your time.

If you haven't purchased the cam yet, have it ground on a 112 intake centerline. If you have it already, buy an adjustable timing set and install it at 112 intake centerline. This will allow you to make more power up high, while maintaining it down low. If the cam is ground +4, your motor will probably make peak power around 6000 rpm. No advance (112ICL) will allow it to peak closer to 6200-6300. Ideal for a 346.
