Weiand Stealth intake manifold is designed lighter and is great for street or strip rods. The dual plane manifold combines the low-end throttle response of a 180-degree design with the top-end power of a single plane. This manifold is best suited for engines that are equipped with aggressive camshaft profiles, headers, and high performance systems. It also features a square-bore carburetor pad for aftermarket 4-barrel carburetors.
