These Holley aluminum Ultra HP carburetors feature all-new construction for maximum performance, right out of the box. They start off with a 6061-T6 billet aluminum black, bright-dipped anodized base plate. They feature elongated mounting holes, allowing for fitment in intake manifolds with a square 4150 or large Dominator-style flange. The base plates feature a dedicated, race-only throttle lever with all unnecessary street attachment points and tangs removed. A stainless steel adjustable secondary link offers you a choice of 1:1 or progressive secondary throttle actuation for ultimate control of the secondary opening rate.
