Addition Information:
- If you live at high altitudes, or are looking for the best efficiency possible, this cam will help you considerably
Modification Required:
- For it to be “drop in” on a 12v you will need no more than .020″ piston protrusion and at least .055″ valve face depth with a standard head gasket and a 99 intake centerline. If you do not meet the minimum requirements for piston to valve clearance, don’t worry, you can still run an oversize head gasket or cut valve reliefs.
- Although this is considered a drop in cam it is important to check clearances
Applications:
- our most efficient, low rpm grind that still makes power than an OEM cam at high rpm
- ultimate low rpm throttle response
- Large or small singles
- Meant for increased all around efficiency
Break in:
To make sure that you have no issues during break-in, follow these few suggestions.
- Make sure that the cam has a Liberal amount of quality assembly lube applied to the lobe and to the block on journal 6 and 7.
- DO NOT let the engine start without oil pressure
- When this is a new engine, be sure to put a liberal amount of assembly lube in the oil pump and prime the oil filter. We recommend 20w-50 Valvoline VR1 oil for break in and Valvoline 15-40 afterwards for the best results
- Be sure to change the oil after 1,000miles. When the filter and oil system are already primed, engine will get oil pressure much faster than if the oil is changed at the same time.
- 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.
- 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 for five minutes at 1200-1500rpm then shut engine down
- Adjust valves then you are cleared to abuse your engine. Enjoy the added airflow
- if you need to re-torque or “hot-torque “the head, do so before adjusting valves. Re-torqueing the head changes the valve lash setting, so it is important to set lash last.
