*** IN STOCK SHIPS TODAY *** If you have a motor that the industry only makes a 4-71 blower manifold for or maybe you have a motor that could use a little more boost and you would like to pull off your 4-71 blower and install a 6-71 blower here is just the ticket.
BDS has machined up this adapter that will allow that to happen by simply bolting this .625" thick plate to the top of your 4-71 blower manifold with four 7/16" bolts. Adapter plate is machined for eight 7/16" holes so mounting the 6-71 blower with studs or bolts is no issue. Adapter plate is O-ringed on the blower side and has ramped inlets to the 7.50" x 3.875" opening which is common on most 4-71 blower manifolds. The surface between the manifold and blower is polished.
Plate measures 15.250" x 12.250" if the buyer wants to try and adapt for another application. Bolts to mount the plate to the manifold are included as well as the O-ring to seal the 6-71 blower to the plate.
Keep in mind you are raising the blower up .625" which will take up 1.250" in belt so a longer belt or pulley chance may be needed once plate is installed.
Buyer will also need fasteners to mount 6-71 blower to plate which RBS can provide at an additional cost if needed at time of purchase.
