big block chevy flywheel
 

What kind of flywheel to run on a big block tall deck w/72c and TRS. Engine is about 550HP. Not sure what I have yet but will know this weekend when engine comes out. Teeth are gone on the ring of the flywheel (assuming I have a ring and not one piece). How many teeth should I have? Is there a standard? Should I have a race type (HP) one? Is there such a thing? I believe the flywheel I have should be for a manual transmission even though the boat is obviously automatic (BW 72c). Any help, suggestions? Thanks.

You can change just the ring on the flywheel, its probably the standard 168 tooth.
take a torch and heat the old ring,knock it off w a hammer. Heat the new one it slips right on.
GM sells the ring itself

You just replace the ring gear. Should be 168 tooth. Much less $ than replacing the flywheel. This is a standard part available at NAPA or GM dealer. About any machice shop or auto repair shop should be able to do the work while you wait. $50 or less + part.

Thanks guys! That was the original plan. Wanted to make sure I was going the right way.
