POLISHED ALUMINUM STREET STRIP PERFORMANCE: Polished aluminum dual plane air gap intake manifold designed for Big Block Chevy 396 402 427 454 502 large oval port engines operating in the 1500-6500 RPM range. Built for performance-oriented hot rod, muscle car, and street strip combinations. This is a performance build component, not a stock replacement manifold.
LARGE OVAL PORT COMPATIBILITY: Engineered specifically for large oval port big block Chevrolet cylinder heads. Not compatible with rectangular port heads. Not recommended for small oval peanut port heads due to airflow mismatch. Designed for standard deck performance builds using carbureted configurations.
4150 SQUARE BORE FLANGE DESIGN: Accepts standard 4150 and 4160 square bore 4 barrel carburetors. Commonly paired with 650-850 CFM performance carburetors depending on displacement, camshaft profile, and intended RPM range. Proper carburetor selection, throttle linkage setup, and spacer planning are required for custom builds.
PRECISION MACHINED PERFORMANCE SPECIFICATIONS: Polished aluminum exterior surfaces with dual plane air gap runner layout for improved charge distribution. Approximate front height 4.750 in and rear height 6.000 in. Features nitrous bosses, dual distributor hold down provisions, and four corner water outlets for flexible performance plumbing configurations.
DOUBLE BOXED PROTECTIVE PACKAGING: Each manifold is secured in dense expendable foam and double boxed to reduce risk of shipping damage to machined surfaces and polished finish. No installation instructions included. Designed for experienced builders and hot rod enthusiasts. Use high quality performance intake manifold gaskets appropriate for large oval port cylinder heads and verify hood clearance prior to installation.
