Re: Gen 6 HR cam in a Mark IV???
The Gen VI crank typically has the ignition trigger used as a spacer on many versions - could that 1/4" accommodation for spacing be the issue here when using a Gen IV crank? If so, the crank gear will be 1/4" out of alignment using the Gen VI timing set.
OLDED - It's STOCK if it's made by GM and it fits!
