Description

The Andrews EV5 Cam is designed for use with either solid or hydraulic lifters, offering flexibility for various engine setups. With its optimized design, the idle remains stable up to 6,000 RPM when used with stock valve springs. Precision-engineered using computer-aided design and CNC-ground from high-quality alloy steel billets on Landis CNC cam grinders, this cam ensures exceptional durability and precise performance. This gear-type cam is specifically designed to elevate the power output of your Big Twin engine. Installation requires careful attention to detail, specifically checking coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure optimal operation and longevity.

Important to know

Installation requires checking coil bind, valve-to-valve clearance, and valve-to-piston clearance. On late '77 and later engines, the pitch diameter on the camshaft, pinion gear, and the breather valve gear was changed. These components are not interchangeable with earlier-style components unless replaced as a set. Late '77 and later gear sets are identified by a circular groove machined in the outer face of the cam gear.
