High quality GM licensed and approved reproduction part, supported with the correct GM part number (W GM part number: 389268RH). Manifold is visually and functionally correct. Get NOS quality without the NOS price. Correct replacement for 1965-67 442, Cutlass or any Oldsmobile with a big block. Eliminate hassles and costly repairs for rust pits, cracks and broken exhaust flange bolts. No need for resurfacing the cylinder head to manifold flange. Eliminates exhaust leaks which occur with original used manifolds.
This manifold is the correct driver side GM X (GM part #)389269LH manifold for 1965-67 Oldsmobile big blocks with the correct functioning damper. The correct right hand manifold for 1968 is the Y manifold but it can be replaced with this W manifold. It is the same shape and contour and will fit and function properly.
Will fit any 1965-76 big block Oldsmobile but is correct for 1965-67. '65-'67 manifolds have different external castings and have an open plenum on the two middle ports.
