Because I've got a stock block 347 on the stand nearly ready to go in Ive got to ask, I presume this was a 28 oz. imbalance crank? Did you use main studs or bolts? If bolts were they stock stuff or aftermarket? Not sure it would really make any difference, more personal curiosity.

I'm also curious if these cranks are failing after the shift on manual transmission cars, where there's the stress on the block torqueing on the mounts vs. an automatic that tends to be a little smoother.

Mine had already been shifted for a good 500 rpm. I'm to old to really bang gears anyway...

500 RM?!?
