Weiand Hi-Ram Tunnel Ram Manifold

Designed around Weiand's exclusive patented ''D''-shaped port runners and large plenum chamber, Hi-Ram provides the optimum fuel charge needed for maximum power in normally aspirated competition engines where high RPM use is necessary. RPM range is up to 9000, depending on individual application. Weiand manifolds accept standard flange Holley carbs and require use of Weiand linkage kit.
