Those dyno numbers seem awfully optimistic for a cammed 5.7. IIRC, 419rwhp is about what a cammed LS2 6.0 would make but the results speak for themselves.

would it not be easier to supercharged the GTO rather than go through all the cam, gears, modded TB, fuel pump, injectors, headers, cats.. ects...?
The GTO sounds very nice though.

lol, no i started in high gear and let her kick down. I didn't want to the kid to feel too bad about his really fast car getting beat up on by a 4 door. He is getting more work done to his car this winter, more races will be posted in the spring. BTW I didnt even launched i just rolled on the gas...
Oh, did I mention that I have the older brother S55.
