Comp Cams K12-300-4 "High Energy" Hydraulic Flat Tappet Camshaft and Kit
Fits 265-400 cu.in. small block Chevrolet V8s

The "High Energy" cam from Comp Cams is a high torque cam that will work very well on the street. It is designed for engines with 10:1 or less compression and can be used with stock carburetors, intake, and exhaust. This cam will produce more power than a stock cam without sacrificing the engine's idle and it works great for everyday driving. There will be no affect on engine vacuum for accessories like power brakes and it also will not affect the engine's idle while the A/C is in operation. It's not the best choice for racing applications but in those applications where performance upgrades are not planned, a Comp Cams "High Energy" camshaft will deliver the kind of improved performance and efficiency that you've come to expect from Comp Cams.

The Comp Cams "K" or "complete kit" includes the camshaft, appropriate lifters, matched valve springs, valve spring retainers, valve locks, valve stem seals, a timing chain set, Comp Cams assembly lube, full instructions, and decals.
