The SM420 with the stock cast iron bellhousing is designed to use the 168 tooth flywheel. The size of clutch will depend on how the flywheel is drilled. Some will accept a 12" clutch, others will only accept an 11" clutch.

I guess I'm in the dark about flywheel size/tooth count/clutch size (10.5"/11"/12"). I need to use a 400 SBC flywheel, as that is what is sitting in the 377.
Any idears?
