Information:

• RPM Range: 1700-4500
• Drops EGT 200-300
• Increased  power we have seen 40-60hp depending on fueling and turbo.
• Duration at .050″ of lift  188 Intake, 220 Exhaust

Modification Required:

• For it to be “drop in” on a 12v you will need no more than .018″ piston protrusion and at least .055″ valve face depth with a standard head gasket and a 99 intake centerline. On a 24v you will need no more than .018″ piston protrusion and at least .038″ valve face depth with a standard gasket. 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
• For the Steel version you will need at least two bushings installed in the cam tunnel, otherwise the steel could eat into the cast iron block
• We always recommend new lifters when changing a cam.
