Hamilton Cams Towing Cam Combo for 24-Valve Cummins

What’s included in the Hamilton Cams Towing Cam Combo for 24-Valve Cummins:

• 178/208 Camshaft (fits 89-2018 Cummins)
• Heavy duty pushrods (500-750 hp)
• 103 Valve Springs
• Lifters/tappets

Hamilton Cams Towing Cam Combo Information:

• RPM Range: Idle-3000
• Drops EGT 200-300
• Better fuel economy 2-3 MPG
• Increased bottom end power
• Quicker spool up
• Duration at .050″ of lift  178 Intake, 208 Exhaust

Addition Information:

• Due to its short duration and wide lobe separation angle, it also has the least overlap (when intake and exhaust valves are open at the same time) of any of our cams to kill in cylinder EGR on engines that have higher drive pressure than boost pressure.
• If you live at high altitudes, tow heavy or are looking for the best efficiency possible for highway driving, this cam will help you considerably

        Example:

• On a truck with a 62mm turbo and 80hp injectors, this cam picked up 40hp at 1700rpm due to the fact that it moves so much air at lower rpms and helps the turbo spool much sooner.

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 Hamilton’s clearance calculator to make it a little easier)
• We always recommend new lifters when changing a cam.

Applications:

• Used in daily drivers
• Towing
• 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
• 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.
