The WP143-M8 is our full-race .600" lift grind for 143 cubic inch and larger engines running 13:1 compression or higher. Power slams in at 3,500 RPM and charges to 7,000 with an unmistakable, savage race lope. This is a race-only camshaft — plan on high-lift valve springs, high-compression pistons, adjustable pushrods, performance lifters, massive intake and exhaust flow, and a mandatory clearance check.

Key Features & Rider Benefits:

  • Full Race Grind: Built for big-inch drag race engines, not the street.

  • Large Displacement: Sized for 143ci and larger high-compression builds.

  • Savage Top-End: Power from 3,500 RPM all the way to 7,000.

  • Race Compression: Designed for 13:1 or higher static compression.

  • Race Sound: An unmistakable, savage race lope at idle.

  • Not Bolt-In: Race only — springs, pistons, pushrods, lifters and a clearance check required.
