Just when you thought there was no possible room for improvement when it came to Small Block Chevy intake manifold technology, along comes World Products and this awesome new single plane manifold.
Designed for use in 383 ci and larger displacement small blocks, particular attention has been paid to the short turns, and a highly effective balance between flow and velocity has been achieved.
Pro engine builders report gains of 15-25 horsepower over any other single four-barrel cast aluminum manifold. What's more, a special "turtle" on the floor of the plenum helps achieve excellent low-end throttle response and performance. The net result is a multi-purpose intake manifold that is every bit as streetable as a dual-plane design, but delivers solid power right through the rpm range.
It is truly a best of both worlds situation. 1955-1986 S/B Chevy.
