The latest addition to the Williams Engineering line of billet induction products, each single plane manifold is custom designed, and cnc machined to perfectly match any type of engine configuration.

Billet manifolds are ideal for single, 4 barrel carburetor applications, as they offer several advantages as compared to production cast, sheet metal, and single top, tunnel ram manifolds. While cast single plane manifolds are effective, you are limited to the amount of customization, due to the fixed plenum, as well as the fixed sizes and contour of the cast runners. Sheet metal, single plane manifolds have high distortion, and have difficulty maintaining the consistency of the runner sizes and curvatures. Single top, tunnel rams are also effective, but often struggle with the fuel distribution on the outside cylinders 1,2,7,8. Utilizing CAD & CFD software, we can custom design the plenum, runner sizes, and runner curvatures that will optimize your induction system.

Facts & Features:

•    Constructed of 6061 billet aircraft grade aluminum
•    Location and length of runners are custom designed to optimize the carburetor signal to all cylinders.
•    Fully ported. Minimal port matching
•    Lighter than cast intake manifolds
•    Plenum Contouring available for optimal air flow
•    Machined nitrous bosses available
•    Available for small & big block V-8 applications
