This manifold is machined for a SFI burst panel which is included with a billet alum. frame. Manifold comes Dow-7 satin finish and will fit a 10-71 thru 16-71 roots supercharger but buyer could use a smaller 6 or 8-71 blower with an adpt. plate. Plenum opening is 13.50" x 4.00" that is machined for an O-ring to provide a superior seal between the blower and manifold and ports measure 2.625" x 1.875". Ports were once O-ringed but look like they have been filled with epoxy and mounting holes look to have some adjusting done to get the bolts holes to line up to the heads at some point in the manifolds life. This manifold is 6.50" inches tall. Manifold has no water provisions and each port has been machined for dual 1/8" port nozzle provisions.
