BBC Intake Manifold - 10.200 R/P 4150 Flange

The BBC Intake Manifold - 10.200 R/P 4150 Flange is engineered for serious big-block Chevrolet performance builders seeking maximum airflow efficiency and reliability. This manifold serves as the critical junction between your engine's cylinder head and carburetor, directing the precise fuel-air charge into each cylinder for combustion. Whether you're building a street engine, weekend warrior, or race application, this casting provides the flow characteristics and structural integrity that separate reliable power from mediocre builds.

The manifold design incorporates runner geometry optimized for the 10.200-inch rise dimension, a specification that determines vertical clearance for hood fit and intake valve positioning relative to the deck surface. The 4150 carburetor flange is the industry standard for compatibility with virtually any square-bore four-barrel carb, from classic Holley performance carburetors to modern EFI conversions using adapter plates. At 26.9 pounds, this aluminum casting balances thermal management with weight efficiency—critical for both street cars and race engines where every pound affects acceleration and handling characteristics.

This intake manifold is specifically designed for big-block Chevrolet engine builds ranging from 396 to 454 cubic inches, making it a go-to choice for Chevelle, Chevrolet truck, and Corvette restorations. The robust construction ensures consistent casting quality and long-term durability under high-RPM operation and wide open throttle conditions. Builders can trust this manifold to deliver the performance needed for serious applications.
