High grade ARP bolts used to attach flywheel to crank shaft..all broke. race car came intoi the pits with engine running and no power to the drive wheels. we pulled off the body panels and could see the rear of the crank shaft. it turned when we turned the front pulley on the crank snout..but the fly wheel did not. after disassembly sure enough..all 6 3/8 bolts were sheared. We have been told this was common. The titanium coated drills were a joke. we used an eazy out to remove the sheared potion. we took third in next days race because a S car almost spun us..last race of the year..the good news is that the car is in one piece and everything is pointing the right way on it.
