The Hamilton Cams 07-CC-24V188 Hot Street 188/220 Camshaft Combo is a valvetrain upgrade for the weekend warrior with a 1998.5-2018 Dodge 5.9L/6.7 Cummins. This camshaft combo can be used in a Daily Driver but it really comes alive at the sled pulls, such as Stock class pulling and the drag strip. This combo kit is perfect for larger single, or compound turbos and includes tappets, camshaft, and valve springs. The 103 lb valve springs help to prevent valve float in higher horsepower and higher RPM applications. The Heavy-Duty Pushrods will not flex like the stock pushrods, preventing loss in valve lift or retarded timing.

Although this camshaft is considered a drop-in replacement, it is important to check clearances. In 1998.5 - 2002 Cummins applications, you will need no more than .025? piston protrusion and a minimum of .038? valve face depth with a standard gasket. The 2003 to 2018 Cummins engines will need .018?piston protrusion and a minimum of .038? valve face depth with a standard gasket. If you do not meet the requirements for piston to valve clearance, you can still run an oversize head gasket or cut valve reliefs.

What’s included:

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

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:

• works great on 24v applications with 66mm or smaller charger for low rpm or with large singles at higher rpm.
• moderate singles, or set of compounds on 24v engines except vp-44 trucks, you will need a 178-208
• 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.
