COMP Cams 21-243-4 - Camshaft CRB 305H-10

Camshaft - Magnum - Hydraulic Flat Tappet - Lift 0.525 / 0.525 in - Duration 305 / 305 - 110 LSA - 3500 / 6500 RPM - Mopar B / RB-Series - Each

Pro Street. 383 needs 3500-3700+ stall. 440 needs 3000-3300+ stall. 850 CFM carb, 10:1+ compression. Headers and good int, 3.90-4.30 gear.

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.
