BLACK STAINLESS MANIFOLD LONG TUBE HEADER/EXHAUST FOR 67-77 ACTION-LINE SBC V8
This exhaust manifolds for the 1967-1977 Chevrolet Small Block Pickups were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our long tube 4-1 off-road headers are designed to allow the exhaust gasses to flow more freely from each 4 cylinder bank and combine in a more efficient manner. Tubing has been optimized for the 5.0L(305), 5.7L(350ci) and 6.6(400ci) 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.
