What’s included:
- 188/220 Camshaft (fits 89-2018 Cummins)
- Heavy duty pushrods (500-750 hp)
- 103 Valve Springs
- Lifters/tappets
Information:
- 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
Modification Required:
- 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.
Applications:
- Used in daily drivers
- Larger single, or set of compounds
- Weekend warrior
- Drag strip
- Stock class pulling
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
- 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.
