360-508 mopar cam builds

060 360 with shaved j heads. It was about 9-1 compression. The piston's were a .100 in the hole @ tdc. The car was a 71 duster street car with a four speed and a 4.10 gear. I was running the comp 305h with .525 lift it was very choppy at idle and produced great mid range power it even had a torker II intake. Anyways it ran 7.90-8.00's on pump gas in the 1/8 mile at 86 mph. Put a mopar .508 in it and slowed down.

I think youd be happier with the 292h cam. The 305h was really to much camshaft for my combo but it was .2 quicker than the .508 mopar cam.

I sent the .508 to bullet and had it reground as a solid and running stock j heads and 1.88 valves on a 11-1 340 in a 70 dart, 5.13 gear and 28x9 slicks it ran 7.68 at 91 mph. Them heads really suprised me for being stock unported.
