Small Block Ford Aluminum Manifold and Riser Kit
These manifolds have individual primaries for more torque and horsepower over your stock center rise or log style exhaust manifolds. This is a great choice as an upgrade from log style manifolds. These manifolds have a steep down slope originally designed for jet boat applications. Riser fits 3-1/2" exhaust hose. From center of exhaust port to end of riser is 13-1/2"
