🏁 Shop67 650 – The Big-Inch Race Cam
Specs:
Lift: .650”/.650”
Duration @ .050: 259°/267°
Intake Close: 54° ABDC
The 650 is the top-tier race cam in the Shop67 Twin Cam lineup — a no-compromise, big-inch powerhouse built for serious 117–131 ci+ engines running high compression, fully ported heads, and aggressive exhaust systems.
This cam is all business: violent midrange charge, explosive top-end pull, and the kind of throttle response that demands attention. It’s designed for race and competition-level builds where airflow and rpm are king.
Expect hard-hitting torque, razor-sharp throttle, and a savage pull through 7,000 rpm — the 650 is the cam that separates the fast from the fearless.
Requires premium valve springs, precise setup, and complete clearance verification.
Built for professionals chasing every last horsepower.
Special order made to order allow 2 week lead time for custom ground cams
