For maximum performance in normally aspirated competition applications, Weiand Hi-Ram Tunnel Ram intake manifolds are the manifold of choice. They're designed primarily for drag racing, truck/tractor pulls, and performance marine applications where high rpm is required but bottom-end torque isn't. With their patented D-shaped port runners and large plenum chamber, the manifolds provide optimum thrust of the air/fuel mixture to the intake ports. They mount either single or dual square-mount carbs and, depending on the application, have power bands that run from 2,500 rpm to as high as 9,000 rpm. Separate tops and runners are available for some manifolds. Order the model recommended for your year/make, engine, and cylinder head application.
