I ran a 9.6 to 1 comp 383 with 452 heads and the MP .484 in a 383 Dart. I ran 38 total all in by 2000 rpm. I used the RPM intake with a 750 DP. With the 3.91 gears and a full body and interior Dart it ran a best of 12.31 @ 110. And it ran fine on 93 or 92. I have to agree with Chip on this as its too much cam for the combo and not enough converter. But since you have it together try bumping the timing to 38 and see if it likes it. If you can get the combo sorted out your car should be deep in the 12's. Good luck , Ron
