This exhaust manifolds for the 1968-1978 Small Block Ford Windsor engines were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-1 Block Hugger off-road headers are designed to allow the exhaust gasses to flow more freely from each cylinder bank and combine in a more efficient manner. Block Hugger style headers are meant to be used where space for long tube headers isn’t available due to steering and cross member clearance issues. Tubing has been optimized for the 289, 302 and 351 Windsor V8 engines. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.
