The 'Big Mutha' Thumpr' name hints at what you can expect: a very rough idle that lets everyone know this engine means business. To get the most out of this camshaft and ensure proper operation, it requires a minimum of 9.5:1 compression, a torque converter with at least a 2800 RPM stall speed, a performance intake manifold, appropriate gearing, and headers. These components work together to allow the camshaft to perform at its best, unlocking its potential for higher RPM power. This kit is a substantial upgrade that changes the engine's personality, making it ideal for modified vehicles used in drag racing or spirited street driving.
This kit is designed to fit a wide range of Ford vehicles equipped with the 351 Windsor engine, including popular models like the Ford Bronco (1981-1995), Ford F-150 (1981-1995), and Ford E-Series vans (various models 1975-1995). Remember that this camshaft is not CARB approved and cannot be shipped to California. For optimal results and engine longevity, always refer to the manufacturer's installation instructions and ensure all supporting modifications are correctly implemented.
