Starter gear to ring gear clearance

[bhoulis]

Posted the same question on CMF so I'll cover my options here too. 67 GT350. 4spd. Using a RAM 157 tooth flywheel, model 1527, stock replacement type as sold by NPD. Ring gear is stepped back 3/8" on the flywheel. Front of ring gear is 11/16" back from the starter mounting surface (block plate). I currently have an older NAPA rebuilt starter that has barely been used. When I measure from the mounting surface of the starter to the edge of the drive gear it's appears to be the same 11/16", maybe a few thousandths less. To me that seems extremely close. Is there a spec for this clearance? Any input welcome. Thanks.

Can you post a side profile picture of the starter nose end of the starter ? That might give some insight to the problem. Yes it seems close.

You've probably checked this but is the starter gear fully retracted on the shaft?
