LS2 Ported heads and cam Went 458 HP and 423 TQ. Stock LS2 w/ LS2 intake & ported 90mm T.B., Hand ported 243 heads, milled .030", notched pistons and Precision 234 246 115 .625 lift camshaft. Dyno room was over 100 degrees. Dyno'd at Zippy Performance and tuned by LVTUNER in Las Vegas. It was pulling timing down to 25 degrees because of the 133 degree IAT's.

Why do the corvettes make such higher numbers with cam only than say Camaros, Trans Ams, GTOs? I've seen heads/cam LS2 corvettes well over 500whp. I have yet to see any other LS2 with a stock bottom end and all accessories (A/C, all belts) run 500whp. Corvettes have less drive train losses??

You are 100% correct sir! Drive Train!! Corvettes have less drivetrain loss..
Less rotations mass from engine to rear. and Half shafts..
Vettes don't have a 10bolt or a 5in diameter steel drive shaft either..
I also think the differential is more efficient.. I think...

It's actually the other way around. The trans-axle and axle shafts kill power! People used to talk about stock 6-speed 2000 SS Camaros out-dynoing stock 2000 6-speed base Corvettes.

all i know is the vette has alot less loss than my car does... a c5 zo6 dynos anywhere from 345-360 stock rated at 405 hp, and my gen 1 cts-v with the same motor did 320 bone stock lol... so the vette is around 12-15% and my v is 20%... vettes dt loss look pretty good to me, or looking at it another way my dt loss is sad

Vegas heat Its programmed for 28 degrees total for a cammed high compression LS2 with 243 heads. We are cooking out here in Las Vegas 105+ and the ECU will pull timing based on water temp 200+ and intake air temps 133+. The owner wanted to watch the dyno pulls and he drove it in hot off the street (25 degrees timing). It could have pulled a better number by waiting until the morning.
