061040 BMP Intake Manifold, SB Chevy, Single plane, 4150 Square bore flange, height 5.625'

While most manufacturers of small block Chevy intake manifolds have designed theirs around 350 CID engines, World Products has developed a very efficient manifold that's proven to increase performance by 15-25 horsepower over the competition in larger displacement (383 c.i.d. and up) engines.

In addition to out-powering the competition, it is important to note that these single plane manifolds are designed to operate most efficiently in the 2500-7500 RPM range, yet have the low-end throttle response and torque comparable to a dual plane. Look inside the plenum and you'll see a "turtle" on the manifold floor that helps bottom-end performance.

Models that accommodate a 4150-style carburetor are available for standard SBC (P/N 061040) and Vortec (P/N 061041)heads. Also available machined for an Accel EFI unit (P/N 061040-EFI) or with a 4500 Dominator-style flange (P/N 061050).
