Howards Cams Rattler Camshafts
Howards Cams Rattler camshafts build solid power and a classic sound while retaining drivability. They feature wider lobe centers and use a more aggressive ramp rate to help with air velocity. Although their design is for high-performance street use, they also work well with a stock torque converter. Howards Cams recommends using their Rattler camshafts with a converter stalling above 1,800 rpm and a set of steeper rear-end gears.
