Thanks guys, this one is so good it makes more then my 427 LS7

There's a good chance it'll go 525, there was only 23 or 24 degrees of timing at the high rpm's. ALso heard too much timing down low, so the whole graph might go up? I'll post the final dyno numbers when I get them in my hand.

Thanks SSZ! The car ended up going back to the dyno and left with less power , then it went to the track... 11.4@124... It bogged out of the hole and the rev limiter was set to low as it hit it in ever gear change... I could see low 11's @ 127+ once its sorted out and tweaked back up to 515+. I know this motor will make 525rwhp once its sorted out!
