The one thing I noticed is that the Powermaster gear doesn't pop out half as far as the stock Chevy starter. It was riding on about half of the teeth on the flexplate. The Chevy starter comes way out, plus the pinion shaft is supported on the end by the snout. The Powermaster has no support out there whatsoever.

It really puzzled me because for years and years I simply went to the auto parts store, bought a starter off the shelf, bolted it on and never gave it another thought. I'm not sure if it has anything to do with the B&M flexplate I'm using or what.
