Chevy Big Block Carbureted Dual Plane Aluminum Intake Manifold - Polished

TSP's dual-plane high-performance intake manifold for the big block Chevy is ideal for street performance applications, with a design that improves throttle response, as well as power and torque over a wide rpm range - idle to 6,000. It is cast from lightweight aluminum and features a low profile for ideal hood clearance. Additional provisions include dual distributor hold-downs, 4 corner water ports, and a choke block-off kit. Set up for spread bore carbs, this manifold comes with an adapter plate and gasket for use with square bore types.
