Holley's New Lightweight Aluminum Carbs!
Holley’s exciting new 670 and 770 CFM “Ultra Street Avenger” and 650 and 750 CFM “Ultra Double Pumper” carburetors are ultra light; the aluminum construction means these carburetors will save almost five pounds over a conventional zinc carburetor. These new carburetors are ultra smooth; the fully adjustable external linkage works without binding.
They are ultra shiny; the tumble polish finish holds a shine longer. They are ultra strong; the metering blocks and base plates are machined from high quality billet. And they are ultra cool; they enable you to personalize your engine with red or blue anodized metering blocks and base plates with gold irridite hardware or black anodizing on the metering blocks and base plates with all black hardware.
Holley’s new “Ultra Street Avenger” and “Ultra Double Pumper” carbs are easy to tune; emulsion, idle feed and the power valve restrictors in the metering blocks give you the ultimate in adjustability. These carburetors feature high signal billet booster inserts, slabbed throttle shafts, and hand polished venture inlets for maximum airflow with less turbulence. These new Holley carbs deliver race winning fuel calibrations right out of the box!
