Is it a steel crank or cast ?

A manual trans with a cast crank was never a good idea in my mind.....

Not sayin it cant be done or if that has anything to do with this failure but if I'm letting a clutch out at 5000-6000rpm and maybe on a 2 step I'm a lot happier with a steel crank in there....

I have used cast cranks and had one in my LT-1 stocker.....automatic trans though...…

Dial bore the rod big ends to see if they might be tapered.....Unless they were cut and rehoned that's pretty unlikely.....

Is the thrust OK....? I assume it was....

Looks like most of the trash was soft bearing material fortunately....

Crank is a steel one. Rods were fine when checked before assembly, I will check again. Thrust is fine.
