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 runn
