torque convertor bolts keep coming loose.

[Crewchief]

I have 70 Challenger with 512ci. big block; 727 transmission, race full flexplate, YANK torque convertor. The car is a dedicated autocross car so I am in and out of the throttle all the time. I keep having torque convertor bolts loosen up then it starts making knocking noise. I have tried red loctite and they still loosen, I am not running any type of lock washer. I am using the bigger size bolts. HELP.

Loctite and proper bolts with correct torquing should not have this problem.

Using the 7/16-20 bolts with red Loctite and torquing them to 65 ft-lbs and they coming loose? Just asking because if so, I'm not sure of a fix.
