What’s included:

• 188/220 Camshaft (fits 89-2018 Cummins)
• Heavy duty pushrods (500-750 hp)
• 103 Valve Springs
• Lifters/tappets

• RPM Range: 1700-4000
• Drops EGT 200-300
• Increased Mid Range power
• Duration at .050″ of lift 188 Intake, 220 Exhaust
• Valve springs are meant to prevent valve float and improve overall performance
• Heavy duty pushrods prevent bends or buckles up to 750hp

• For it to be “drop in” on a 12v you will need no more than .025″ piston protrusion and at least .055″ valve face depth with a standard head gasket and a 99 intake centerline. On a 98 – 02 24v you will need no more than .025″ piston protrusion and at least .038″ valve face depth with a standard gasket. On an 03 and up, it needs .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 (You can use our clearance calculator to make it a little easier)
• We always recommend new lifters when changing a cam.

• Used in daily drivers
• Larger single, or set of compounds
• Weekend warrior
• Drag strip
• Stock class pulling

• Make sure that the cam has a Liberal amount of quality assembly lube applied
• 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
• Be sure to change the oil after you have done your break-in procedure. 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.
