Ok I am replacing a 1990 330 hp 454 Mark IV with a Gen VI motor that is externally balanced. I am sure I need new a flywheel. Can’t seem to find the right pt PN for it. Any one have the part number or a flywheel for that mater? Am I corect in the Mark IV are Internally balanced? Also is the Adapter for the Oil cooler/ remote filter different ( part at the block) different?
thanks
Mike

Eventhough they both may be externally balanced, I believe they have different crank shaft flanges which means the bolt pattern on the flywheels are different.
Filter adapters are different.
Filter adapters are different.
