Have a 97 350 chevy engine. Using 10,5 clutch. Installed a 14088647N flywheel. 153 tooth . Using a powermaster starter for 153 or 168 tooth flywheel. Starter instructions say there should be 1/16" clearance between retracted starter gear and flywheel. I have 1/4". Is this flywheel sized differently than the more standard 14088650? Can't find any info on the 14088647N .HELP, Thanks

 

Both 14088647N and 14088650 are 153 tooth, 12.8" dia.

Powermaster makes some starters which bolt to the (parallel) bolt holes for a 153 tooth flywheel, and they can use a second set of holes (in the starter case block) to mount further out to suite a 168 tooth wheel. But that should be greater than 1/4" difference.

I would say you have a questionable starter fitment situation, but no pics and no PN for the starter mean more questions than answers.
