Chevy SBC 350 1957-95 MID-AIR™ MidRise Aluminum Intake Manifold [Satin] Ford rear-end housingsThe Speedmaster MidRise Air design features the identical plenum and runner design as the normal MidRise. The main difference is that there is an open area under the plenum chamber. This feature is sometimes called an air gap design.
