Anyone have any fixes other than an anti-pullover squirter to fix this issue? 4412 360 stock car motor, motor drops 13:0 afr to 10:1 afr at higher rpm.

See what the vacuum level is when it starts to go rich and select a power valve that closes at that vacuum level. I've run as low as a 2.5 pv and it helped alot. Also you can play with high speed air bleeds.
