In 1963, the G-code engine was a 406 (6V). The 427 was either a Q-code (4V) or R-code (8V). They may have actually used the same crank, since they had the same stroke. I know the 427 cranks had grooved mains, but I don't know about the 406. I have seen one 427 crank that was C3AE-E, but that isn't to say they didn't also have one that was C3AE-G (not C38E-G).Im looking for a 427 G-code crank out of a 63.
Crank number C38E-G Thanks
