HIGHLIFT CAMS 1.4:1 & 1.5:1 ROCKERS

Unlike standard cams, these grinds (such as the legendary Engle FK Series) feature specialized lobe profiles that account for the increased leverage of ratio rockers. This combination allows for a faster valve opening rate and significantly higher total lift without excessive duration, resulting in an engine that breathes better and pulls harder across the entire powerband. Whether you are building a weekend bracket racer or a high-performance sand rail, these cams provide the lift you need to dominate the track or the dunes.

Our Ratio Rocker Cam Selection Features:

• Engle FK Series Cams: The gold standard for ratio-rocker builds, including the FK-7, FK-8, FK-10, and FK-40 profiles.

• Maximum Volumetric Efficiency: Designed to work in harmony with 1.4 and 1.5 rockers to maximize air intake and exhaust scavenging.

• Competition-Grade Durability: Precision-ground for high-RPM stability and long-term reliability in extreme performance environments.

• Specialized Profiles: Lobe designs that minimize valvetrain stress while maximizing the mechanical advantage of high-ratio arms.

• Engine Versatility: Ideal for large-displacement Type 1 engines, from street-able 1914cc builds to 2332cc+ competition strokers.
