Here is our 3 carb blower adapter, engineered to mount a set of three two barrel carburetors atop a S.c.O.T. supercharger.

Carburetors are spaced just under 5 inches apart on center utilizing 5/16-18 threaded holes for mounting. This piece is cast of A356 aluminum, CNC machined in house, and comes with mounting hardware and gasket included! 1.75" tall, 4" wide, and 12.5" long. Available in cast and polished finish. All made here in the USA!
