Based on the marine version, Mopar's in-line dual quad aluminum manifold is built from the original tooling and machined to accept aftermarket AFB or Holley carbs
(it will not accept OE AFB carburetors).
This manifold fits production 426 Hemi heads and retains stock height as the production 1966-71 Street Hemi AFB Intake Manifold. It has provisions for manifold heat and power brakes.
