Product Information

WOT-Tech Little Thumper Roller Camshaft Package includes the following parts

  • Little Thumper Roller Camshaft
  • Comp 26986 Valve Springs
  • Custom Length Pushrods
  • Timing Cover Gasket Set

Our Little Thumper cam is designed for 2500-5500 on stock engines, and 3000-7500+ with supporting mods for better intake/exhaust breathing. 

Custom length pushrods are usuallynecessary with this camshaft.   There are 2 methods to determine the lengths.  The default is for us to measure the base lobes and use the difference in diameter from stock.  If you have any head milling and/or block resurfacing, we need to know how much was taken off.  The second option is the most precise, and requires an adjustable pushrod and the exact legnth for proper lifter preload is determined by measuring it in the assembled engine.  For more information on pushrods and lifter preload, please check thisarticle

If custom length pushrods are not needed, we will refund the difference on this kit.

The timing cover gasket set includes the rear main seal and oil pan gasket. 

Tuning is required for best results

We have a base tune for OBD1 vehicles.  OBD2 will need an HPTuners setup to dial it in.  The MAF will help on the OBD2 computer to work without a tune.  OBD1 are engine swaps, so a retune is necessary for that alone.  We offer tuning services for those with the ALDL cable and Burn2 chip burner for OBD1, and HPTuners for OBD2.  Contact us for details.
