The 512 block was used for 69 427 and continued into 70 as a 454. however, the 427 was internally balanced and the 454 was externally balanced. Because of that, the crank, balancer and flywheel must be for the correct application.

I've seen this before so I thought I would ask. What is the difference between internal and external balancing?
