I've had terrible luck with mini starters. I had a Powermaster 9000 on the 350 in my T for a year before it took a dump.......never could get it to work right from the beginning. Had to shim and reshim and it still was just catching the front edge of the flexplate teeth. When it died I tossed it and bought a regular old Chevy starter and it works just like it should, the pinion comes way out and engages the entire flexplate tooth area.

Some may like em, but not me.
