ported 906 heads....

Thats a nice combo. Just make sure you use enough convertor. We had stock 452 heads on the 383 that was in my sons Dart. They had some mild pocket porting that we did to them and that was it. It also used the MP .484 cam. All stock shortblock with stock bore. It also used all stock valvetrain and Crane sigle springs with stock valves. Had the normal bolt ons like RPM intake and 750 DP along with headers. Had a TA 10" tight 3000 convertor and 3.91's. Car ran a best of 12.31 @ 110 and I loved that .484 cam. It will make decent power with the right convertor. 906 heads are just about the exact same as the 452's. Ron
