6223 is the 396 crank and the 7115 is the 427 crank.

Kim,
Not exactly. I know for a fact that many, if not all, of the L/71 engines
used the '6223 crankshaft. I'd bet that the L/72's did as well.
L/71's, L/72's, and L/78's all shared a very similar,
if not exact piston dome.
I believe that the '7115 crankshaft ( aside from the actual
inherant strength ) has beefier counterweights because the
L-88 & ZL-1 pistons had monster domes.
I've never heard of a '7115 crank being factory installed
in anything but the badest of the bad.
Unless I'm
wrong, that = L-88 & ZL-1
