Separate split plenums feed straight, tapered runners for an even dual-quad fuel-air distribution path.
This Offenhauser® high-rise dual-quad manifold is intended for the Chevrolet 348 engine with compatible AFB or Holley® four-barrel carburetors. Each carburetor sits above its own split plenum, feeding straight, tapered runners toward the intake ports. The arrangement is designed to promote even cylinder filling and responsive mixture delivery. Its raised carburetor positions require clearance to be checked with the selected linkage, air cleaners, hood and distributor.
