Use or break-in oil or conventional (non-synthetic) 10w30 oil with zinc additive for the first 500 miles of operation. Do not drive for long periods at any single speed, always vary your speed. Do not tow a trailer or put other heavy loads on the vehicle. It is best to avoid long periods of idling during this period. Check the engine oil and coolant levels daily.

Engine showed up and went in without any drama. Delivery timing was correct and the carb only needed minor tweaks. Sounds great out of my 3 inch exhaust. Love the cam, it’s exactly what I was after.
