The Speedmaster 1-147-033 is a mid-rise aluminum intake manifold finished in black, designed specifically for Chevy Small Block 350 engines. The aluminum construction helps reduce overall engine weight while the mid-rise plenum design supports strong mid-range to upper-RPM power delivery for street and performance applications.
Engineered as a direct-fit replacement for compatible SBC 350 setups, this manifold offers a performance-oriented upgrade over stock cast-iron units. The black finish provides a clean, distinctive appearance under the hood, making it a solid choice for enthusiasts looking to improve airflow and add visual appeal to their small block build.
