Anyways, I need a flywheel soon because mine it all cracked. Rebuilding the mid 70's 350 for my '57 and the machine shop needs it to balance for my new engine. Clutch size doen't matter as long as it will bolt up to the crank. Posted here as well as in the parts wanted section. Thanks

They say money can't buy happiness. It can buy old Chevy trucks though.

The trucks used the larger one & most cars used the small one. Small flywheel has 153 teeth on the ring gear, the large one for the 11" clutch has 168 teeth on the ring. You'll need the correct starter motor to match the flywheel size too. Stuart. | | |
