I have a 67 327 which I am about to rebuild and would like to order most of the parts before I tear down. Is there some way to tell which flywheel I have as in number of teeth. The car originally was a small 327 with a Muncie 4 speed

About 90 percent sure this is the large flywheel, 156 (?) teeth. Look for angled starter bolts to block. Probably a 10 1/2 in clutch.

A large flywheel would be for an 11 inch clutch. I believe the flywheel would be the 12 3/4" with 153 teeth.
