That's correct. Actually, that session was three passes on the Dynojet at K&N Engineering near the end of the period when the car was a "project vehicle" for "Vette Magazine." It was two runs at 410 and one at 413. There were also a few in the high 400s, but that was with a different calibration.

My 90 Z measured 432 hp at the wheels, using SAE/Marc's 15% drive line loss, my net crank calcs to be 508 hp. Now, going on net crank hp and nothing else, I imagine it would be a near toss-up in the quarter mile, all things being equal. Care to race and compare??

Well, uh...(choke)...
I don't know how this thread ended up being a wee-wee length contest. I thought we were talking about how GM has rated engines, the differences between the old "gross" power rating system and the current "SAE net" power rating system and the ins-and-outs of comparing power output using dynos.
But...I will conceded, Paul, that your weenie is bigger.
Likely you'd wipe my sorry butt all over the track seeing as you have headers, shorter gears, more power to the ground and significant drag racing talent revered by most here on the ZR1 Net Forum.
