Description

Not for sale or use in the state of California

What’s included:

  • 178/208 Camshaft (fits 89-2018 Cummins)
  • Extreme duty pushrods (oem-2000 hp)
  • 155 Valve Springs
  • Retainers and Locks
  • Lifters/tappets

Information:

  • RPM Range: Idle-4000
  • Drops EGT 200-300
  • Increased bottom end power
  • Quicker spool up

Addition Information:

  • If you live at high altitudes, or are looking for the best efficiency possible, this cam will help you considerably

Modification Required:

  • For it to be “drop in” on a 12v you will need no more than .020″ piston protrusion and at least .055″ valve face depth with a standard head gasket and a 99 intake centerline.   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

Applications:

  • our most efficient, low rpm grind that still makes more power than an OEM cam at high rpm
  • ultimate low rpm throttle response
  • Helps spool large 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 to the lobe and to the block on journal 6 and 7. 
  • DO NOT let the engine start without oil pressure (change oil after installation. 
  • 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. We recommend 20w-50 Valvoline VR1 oil for break in and Valvoline 15-40 afterwards for the best results
  • 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 #6 rocker arm.
  • 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-torquing the head changes the valve lash setting, so it is important to set lash last.
