Product details
An older member of the COMP Cams grind family, the Magnum series of camshafts offers excellent performance gains over stock without the added wear and tear associated with more aggressive camshafts. Ideal for use with higher compression ratio engines that need to bleed off compression, the magnum series performs its best when static compression is 9.5:1+ and with an aftermarket higher stall torque converter. Delivering excellent high RPM power, while not needlessly abusing valve train parts, the Magnum grind family is the perfect choice for performance engines equipped with mild ratio rocker arms and traditional performance valve springs. Good for daily driven street machine, works with stock converter, likes headers. 396c.i. needs 3.55-3.73 gear and 1800+ stall. Slight rough idle. Magnum 224/224 Hydraulic Flat Cam for Chevrolet Big Block 396-454
