Default 454 flywheel casting number??
What flywheel casting number should I be looking for to fit my 1971 454 externally balanced engine? I have seen a couple so far 3993827 and 3973457. Are there several that would work? I am using an 11 inch clutch. Thanks Jack

3973457N is the only one I'm aware of for a 14" flywheel/11" clutch.

That is the Mark IV flywheel.
Your number 3827 is the part number and 3457 is the casting number.
They are the same wheel.
Hope this helps.
