WP610-M8

$375.00

The WP610-M8 is our race-bred .610" lift street/strip grind for 124 to 132 cubic inch big-bore engines running 12:1 compression or higher. Crack the throttle and it pulls from 3,000 RPM to 7,000, with a distinct, aggressive, choppy lope that sets the tone at idle. It wants compression and airflow to do its job — high-lift valve springs, big bore pistons, adjustable pushrods, performance lifters, and a full professional tune. This is not a bolt-in swap.

  • High RPM Pull: Effective from 3,000 to 7,000 RPM.
