CS265 DEH-10 Cam

The CS265 DEH-10 Cam from COMP CAMS is a high-performance camshaft designed for serious engine builders and enthusiasts seeking measurable gains in mid-range torque and peak horsepower. This mechanical roller cam is engineered for street and strip applications where reliable valve actuation and improved breathing efficiency directly translate to noticeable performance improvements. Whether you're building a naturally aspirated small-block or preparing a modified engine for competition, the CS265 delivers the valve lift and duration characteristics needed to unlock your engine's true potential without requiring exotic fuel or extreme compression ratios.

COMP CAMS' CS265 profile features precision-ground lobes that optimize valve timing and lift across the RPM band, promoting better cylinder fill and scavenging during overlap events. The roller design minimizes friction losses compared to flat-tappet alternatives, reducing parasitic drag on the engine and allowing more of your fuel's energy to reach the wheels. This camshaft is manufactured to exacting tolerances using advanced metallurgy, ensuring consistent lobe geometry that maintains performance durability through extended street driving or race duty. The DEH-10 designation indicates this cam is specifically configured for mechanical hydraulic roller lifters, requiring proper rocker geometry and valve train clearance verification during installation.

Experienced engine builders favor the CS265 for both carbureted and fuel-injected platforms where responsive mid-range throttle response matters more than peak RPM numbers. Installation demands careful attention to pushrod length, rocker arm ratio, and valve spring pressure—critical factors that determine whether you realize the cam's full performance envelope. Proper break-in procedure using a zinc-rich oil additive is essential to protect the cam lobe surfaces during the first operating hours. This camshaft pairs effectively with stock or mildly ported cylinder heads, intake manifolds optimized for your intended RPM range, and a tuned exhaust system that complements the improved scavenging characteristics you've invested in.
