Overview

The Dart 42811000 is a dual-plane intake manifold designed for Small Block Chevy engines. Constructed from aluminum, it features a natural finish and is engineered to mount a single, square-bore 4-barrel carburetor. This manifold is suitable for a wide RPM range, from 1,500 to 7,000 RPM.

Show original supplier description

The Dart 42811000 is a dual plane intake manifold engineered to work seamlessly with Dart small-block heads for optimal performance. It features a unique design with a boundary layer of cool air beneath the plenum and runners, which insulates the fuel/air mixture from engine heat, resulting in a denser intake charge and increased power. The dual plane configuration is specifically optimized to maximize mid-range torque, while a ribbed plenum floor aids in fuel atomization. This intake manifold accepts popular 4150 square bore carburetors and is recommended for engines with 215cc and smaller intake ports. Additionally, it includes dual distributor hold-downs for simplified timing adjustments and has integral bosses for nitrous injectors. Note that this manifold is intended for race or off-road use or for vehicles manufactured before 1966.
