Stage 3: Nicknamed the “BIG STICK“.

It has gained the most popularity. This cam delivers the strongest mid-range torque and H.P possible, but still has good bottom end and drivability.

No mods are required, but we do recommend a set of springs if revving over 3000 rpm.

Includes TAPPETS: We recommend only COLT CAMS CUSTOM 1.4 diameter max crown lifters

Includes RETAINER: All our cams are drilled and tapped to accept our custom retainer to keep the gear from walking off.

  • Average 2 – 3 MPG increase
  • 30 – 35 % smoke decrease
  • Approximately 200° EGT drop
  • Good to 4000 rpm
  • BREAK IN PROCEDURE
    • Cam Lube on all lobes, lifter faces and oil pump gears.
    • Oil all bearing journals and lifter barrels.
    • Always turn engine over by hand before starting, check for clearances and proper timing location.
    • Fire up to 1800 – 2000 rpm. for 18 – 20 minutes.

    Note: Most oil companies have taken out a percentage of additives that are meant for anti-scuffing for break in on flat tappet cams, so please ask your local auto parts professional for the best zinc additive they have and add it to your oil before you fire up your engine for the first time. (We prefer ZDD Plus.)

    • Valve lash all grinds: INT: .010″ EXH .020″ cold.
    • Follow Cummins installation instructions, use adequate amounts of assembly lube.
    • Retainer torque 44 ft lbs – use red loctite.
    • When using our retainer, clearance is required on C.R.

 

NOTE!!!!! When we say our camshaft is a straight drop in, we mean: In almost all cases.
However, due to many contributing variances in an engine: heads planed, block decked, valve recession etc… any cam including stock, should always be checked for clearance before start up!
