Show original supplier description
The Crane Cams 113821 PowerMax camshaft is a hydraulic flat tappet camshaft engineered for performance applications. This camshaft, identified by the grind number H-288-2, offers a 288-degree advertised duration on the intake side and 296 degrees on the exhaust side. Its performance is further defined by a duration at 0.050-inch lift of 226 degrees (intake) and 234 degrees (exhaust). With a valve lift of 0.458 inches for the intake and 0.473 inches for the exhaust (using factory rocker arm ratios) and a lobe separation of 114 degrees, this camshaft is designed to operate effectively within an RPM range of 3,000 to 6,000. This specific camshaft is often associated with Chevrolet V8 engines, including those from 262 to 400 cubic inches manufactured between 1957 and 1987, though specific fitment should always be confirmed. Some sources suggest it provides a fair idle and is suitable for applications requiring a 9.5-11.0 compression ratio, with a cruise RPM range of 3400-3800.
