COMP Cams 01-427-8 - Camshaft CBVI XR300HR-14

Xtreme Energy 248/254 Hydraulic Roller Cam for Chevrolet Big Block GEN VI

Works well with large c.i. engines. Great for bracket racing, with all upgraded parts, needs 3500+ stall.

Featuring a quicker valve opening, the Xtreme Energy camshaft profile provides increased responsiveness and more area under the lift curve than older, slower grinds. Designed to increase performance without sacrificing driveability and creature comforts, the Xtreme Energy grind family offers gains in torque and horsepower while still delivering adequate vacuum for power brakes and other vacuum dependent accessories. Xtreme Energy camshafts work great in carbureted applications, but offer the best performance with aftermarket intake manifolds, lower gear ratios, headers and free flowing exhaust.
