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. |
