Your crankshaft #6223 is a 1970-1972 402 (396) forged steel. This has the same stroke as a 427 crank. The difference is a 427 crank is heavier due to a different counterweight design. The 427 has a 7/8" counterweight and a 396/402 crank has a 3/4" counterweight. I would say you've got a 454 block w/a 396 crank and older BB heads. the combo equals 427 CI.
