You Bet, I have the billet shafts, roller rockers, end stands and supports, plus his pushrods,
oil pump, and billet
oil pump drive. Have a Stock Bore 427 SO with solid lifters, Edelbrock Heads, Intake, and Water Pump. It all works great, take the time to align all the stuff properly and you will like his stuff. Oils better than stock parts at lower RPM because of the rocker oiling design. Have a couple of friens with the same parts, all FE motors, same story.
