I am trying to determine if my flywheel is 168 tooth. The numbers on it are 3789738. Any help would be appreciated.

Are you sure it's not 3789733? That's an 11" 168 tooth

The casting is not that good but it sure could be! Thank you.

Stock here..

Staggered starter bolts mean's it's a big one.

I think you just measure the diameter, if the clutch is off. Very few of our cars were made with the small stuff.

Mark one tooth With white paint marker rotate the motor by hand and count the teeth. Very easy.

Maybe very few (like none) of your big blocks Fred, but ALL 6's, 327's, 307's, and 302's used the small flywheel

I knew I was sticking my head out with that one Jim.:yes: I'll write down your post!

My 350SS L-48 used the same stuff the BB's did back then, big flywheel and stagger bolt h-d starter.

You can tell the h-d starter b/c it will have a copper spacer tube that's like 7/8" long between the case's field coils and the front of the Bendix.
