400 low buck dont give a

A friend put a re-ring 413 in his Dart. Comp with the 906's he used figured out in the 7.5 to 1 range. stock rockers, MP 484 cam, M1 single plane, 950 HP carb, 2-1/4"! custom headers. It ran 12.6's in his Dart the first time to the track, (I was there). He later stabbed in the old "509" cam, and it went even faster, but I don't recall how much. A 150 shot with the bigger cam had him in the 11.0 second range. He had $500 in the long block.
