| | | | Joined: Dec 2006 Posts: 92 Shop Shark | | Shop Shark Joined: Dec 2006 Posts: 92 | Could someone help identify a flywheel and pressure plate. I forget where I got these but it's a matching set with the the numbers GM4 3973456N on the back of the flywheel. The clutch disc and pressure plate are 12" diameter. The pressure plate bolts to the flywheel with 6 bolts. The flywheel to crankshaft bolt pattern seems to be larger in diameter than a 235/261 crank and does not have the three locating pins. I'm thinking it could be a 302 GMC but the crankshaft bolt hole diameter (7/16) and bolt pattern diameter is smaller than the other GMC 302 flywheels I have. Maybe and early GMC flywheel? Any help would be appreciated, thanks!
Paul.

Could it be a chevy v8 flywheel? | | | | | Joined: Mar 2005 Posts: 98 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 98 | thats a late 60s, early 70s chevy v8 flywheel

Maybe I'll put it in the parts for sale classified, it'll do someone some good...
Thanks again, Paul.
