This polished aluminum Big Block Chevy intake manifold is a single plane high-rise performance intake engineered for carbureted 396, 402, 427, 454 and 502 cubic inch engines equipped with large oval port cylinder heads.
Designed for street strip performance builds operating in the 3000-7500+ RPM range, this intake manifold supports strong airflow and top-end horsepower for muscle cars, hot rods and classic performance trucks.
The intake uses a 4150 square bore carburetor flange compatible with standard 4150 and 4160 four barrel carburetors commonly paired with 650-950 CFM performance carburetors depending on engine configuration.
Precision machined oval ports measure approximately 2.00 inches tall by 1.65 inches wide for proper gasket alignment and performance port matching.
Constructed from cast aluminum with a polished exterior finish, this intake manifold enhances engine bay appearance while maintaining the strength expected from a performance intake manifold.
Each unit ships protected in expandable foam and double boxed packaging to help reduce the risk of shipping damage to machined surfaces and polished exterior areas.
