Knowing the specs of your cam would probably help. And to restate what everyone else has said, have the car tuned on the dyno. If you max power for racing then just add nitrous and or meth injection.

Since we're sort of turning this into an LSx thread…. My Vette just decided to throw the P0420 code after I installed ARH headers with high flow cats and a new exhaust system on it. Likely cause 02 sensor or bad cat?

Fucknag posted:Possibly just insufficient cat, at least for what the stock PCM is looking for. It's possible you could get it tuned to accept the new value, though that could cause complications depending on where you live and whether or not you have to deal with a sniffer test. Well a tune is in order anyways before the blower and after. I'm not too worried about this whole passing smog thing.
