Used Indy standard deck 426 type Hemi blower manifold. This blower manifold is cast magnesium and fits Hemi's that use the six or ten bolt mounting configuration with the O-ring around the port in the heads. Will not fit the early ten bolt heads that don't have a O-ring in the head.
This manifold will fit a 10-71 thru 18-71 roots or screw blower but can be used with a set back plate if a smaller blower is to be used. Opening in the manifold where the blower mounts is 14.875" x 4.125" and has been machined for an O-ring to provide a superior seal between the blower and manifold.
Manifold is machined for a standard SFI burst panel in the front with a AN plug in the rear of the manifold to fill the engine with oil. Ports are 2.250" x 2.125" and mounting bolt holes are 4.750" on center on the inner three stud holes. Manifold is 5.750" tall from deck surface to blower mounting surface and is machined for port nozzles with three holes drilled and tapped 1/8" pipe per cylinder. Manifold has one 1/8" pipe thread provision in the front which is currently open at the front of the plenum for the buyer to plumb a boost a gauge into if they choose.
Manifold is in good shape with no repairs or any major modifications done to it. Manifold weights nineteen pounds as seen in the pictures and RBS can supply a whole line of manifold acc. such as manifold to head studs, burst panel/frame, blower studs or a burst panel diverter.
