The Speedmaster 1-147-031 is a mid-rise aluminum intake manifold designed for Chevy Small Block (SBC) 350 engines. The lightweight aluminum construction helps reduce overall engine weight while promoting improved airflow compared to stock cast-iron manifolds, and the satin finish provides a clean, factory-appropriate appearance right out of the box.
This mid-rise design strikes a balance between low-end torque and top-end power, making it a versatile upgrade for street and performance SBC 350 builds. Engineered as a direct-fit replacement, it is intended to work with standard SBC 350 components for a straightforward installation.
