I combed through a pile of starter motors and can't seem to find one that fits. I've got a '68 Chevy 250 inline with a 200r4 behind it. It's got a 168-tooth flex plate that isn't original to the motor or the trans. I grabbed a starter specifically for a '68 250/automatic at NAPA today, but the bolt spacing is wrong. It puts the starter snout in too far toward the crank. (Hits the flex plate.) Some have a staggered bolt pattern, and that isn't what I need. The bolt holes are parallel to the plane of the flex plate. Do any of you know what I need? I'm new to the world of Chevy stuff. Someone has to know...
Two flywheel/flexplates 168 tooth larger od and 153 tooth smaller od. Two starter, one matches the 168 and one the 153. The 168 and starter is a set. And the 153 and starter is a set Not familiar with 250 6 block If your block has 3 holes for the starter mounting you should be able to use either set but never mix the parts of either set. If it doesn't have 3 holes, you'll have to change flex plate or drill & tap the third hole, or get the 4 hole mini starter. You have a 168 flywheel and a 153 starter. A later 350 starter should be a match to the 168 tooth wheel Be sure to use the OEM knurled starter bolts. Dormans aren't knurled enough.
If your block has only 2 holes straight across you have 2 options.. 1. 153 tooth flexplate OR 2. Use an aftermarket mini starter with 4 holes in the mounting plate ( the inner set of holes is for 168 tooth flexplate ) Dave
