The Speedmaster 1-147-004 is a low-rise aluminum intake manifold designed specifically for Small Block Chevy 350 engines equipped with Vortec cylinder heads. Constructed from aluminum for a lightweight, corrosion-resistant alternative to cast iron, this manifold features a satin finish that delivers a clean, professional appearance under the hood.
The low-rise design makes it an excellent choice for vehicles with tight hood clearance, while the Vortec-specific port matching ensures proper alignment with Vortec head ports for optimized airflow and improved engine efficiency. A great upgrade for street performance builds running an SBC 350 with Vortec heads.
