Modification Required:
- There is no modifications required with this “OEM replacement camshaft”
Break in:
To make sure that you have no issues during break-in, follow these few suggestions.
-Disconnect the fuel system and spin the engine with the starter until oil pressure can be read or until oil is coming out of the rocker arms on cylinder#6
-Do not let the starter run for more than 10 seconds at a time
– Once oil pressure has been verified, let the engine start and run until operating temperature is achieved, then shut engine down
-A hot-retorque is very important and will change the valve lash setting, so it is important to set lash last.
-Adjust valves (.010″ intake/.020″ exhaust) then you are cleared to abuse your engine. Enjoy the added airflow
2-3 times a year I get calls from customers that have lash starting to get loose on the last 3 cylinders. This is caused from poor lubrication at the time of initial start-up. In this case the cam literally eats its way through the block away from the force of the tappets. Assembly lube and oil pressure on start-up are a pretty big deal to your cam. Don’t let this happen to you.
