My 460 that I am disassembling for a rebuild is a 1978, I plan on degreeing the cam when reinstalling it, Will I need to order a early timing set in order to get it to dial in to the cam makers specs or will the 3 key gearset be enough? I think they only adjust 4 degrees each way.
I would think with the confusion about the cam timing you would want to dial in all 460 cams, Cam timing is critical to good mileage and performance
