The engine will run good, and you wont need to spin the mill 8K either. 7000-7300 shift points and the engine will live a good while.

That engine will run good. No need to spin the motor to 8K either... 7200-7300 shift points and it will live a long time.

What rocker gear are you going to run?



I agree with the rpm's. I think that was my next hurdle in trying to run 7's with a 572" -1 motor. The 4.56 gear and 7600 rpms at the stripe were just making the head issue worse. Wanted to try 4.30's but they are always back ordered for a D60. Tall gears and let that beast grunt, try to keep it under 7200.
