I followed ARP's torque specs, so much for that. I used red loctite this time, hopefully they don't come loose again.

I was crewing for a stock car running a chevy 250 straight 6 a number of years ago. Had the same problem. No matter what we did it would spit off flywheels, even the LocTite didn't help. It turned out it was some sort of weird harmonic that kept loosening the bolts. We put a Fluidampr front vibration dampener on it and it cured the problem.
