Howards Cams Big Daddy Rattler Camshafts
Howards Cams Big Daddy Rattler camshafts are street performance cams designed to give a nice aggressive-sounding idle without sacrificing throttle response and horsepower gains. Big Daddy camshafts are top dog in the Rattler lineup, and as such they offer a rough idle, and are best used in Pro Street or street/strip applications. Compression needs to be at least 9.5:1, the torque converter needs to stall 2,800 rpm or higher, and a performance intake manifold, steeper gears, and free-flowing exhaust are required to take advantage of the camshaft's capabilities.
