Thanks Robot,

So I guess Ill just ignore that white paint mark at 4 on the balancer. Perhaps this was set by the tech at GM just as a ballpark to start the motor.

Yeah, noticed the vacuum advance on the distributor provided way too much advance at high rpm's so I just plugged it and now its much better, what was GM thinking?? Right now I have it at 14 degrees @ 800 which is giving me about 38 total at WOT, seems fine, but if it pings I guess I'll drop it off a bit.
Thanks!
