Comp Cams K12-246-3 - Comp Cams 'Xtreme Energy' Hydraulic Flat Tappet Camshafts Details
Chevy 262-400ci Small Block 1955-98
In order to use these camshafts in 1955-57 265ci blocks, it is necessary to machine a small groove in the rear main journal of the cam to allow oil flow to the top of the engine. Very strong mid-range, torque & throttle response, needs 2200+ stall.
Operating Range: 1800-6000 RPM Duration Advertised: 274° Intake / 286° Exhaust Duration @ .050'' Lift: 230° Intake / 236° Exhaust Valve Lift w/1.5 Rockers: .487'' Intake / .490'' Exhaust Lobe Separation Angle: 110°
The Leading Edge of Valve Train Technology Comp Cams Xtreme Energy series can be used in any street or street/strip application where both throttle response and top-end horsepower is desired. These camshafts are designed to take advantage of the latest improvements in valve train components and the newest developments in camshaft design. Their aggressive lobe design produces better throttle response and top end horsepower than other cams with the same duration @ .050'' lift, while delivering increased engine vacuum. We do not recommend the use of stock valve train components with these camshafts due to the aggressive lobe designs.
