This new aluminum in-line Dual Quad Hemi Intake Manifold is based on the Marine version and is built from the original tooling. Machined to accept aftermarket AFB or Holley carburetors (P4452778 rear, P4452779 front - see Fuel Systems section of this catalog). Will fit production 426 Hemi heads and has provisions for manifold heat and power brakes. It retains the stock height of the production 1966-71 Street Hemi AFB intake manifold. Production AFB air cleaner baseplate/lid will need to be changed or modified. Some O.E. and aftermarket linkage components and fuel lines are needed to complete the installation.
