Based on the wildly successful Race Series carburetors the new PROFORM street carburetors are constructed of light weight aluminum, and feature changeable idle air bleeds for easy non-permanent calibration changes if needed. Keep your drills in your tool box; fine tuning is accomplished by simply changing air bleeds not opening calibration restrictions with a drill bit.
Each street carburetor features billet metering blocks with a street performance calibration developed for today’s high performance engines. Four corner idle on mechanical secondary carburetor to help fine tune the idle with aggressive camshaft profile. Changeable idle feed restrictions further expand the idle adjustment capabilities. Conventional service and tuning components are available through your local Parts Pro retailer.
You’ll also find the popular billet throttle body for superior strength, coupled with precision throttle shafts to ensure long term performance. All PROFORM carburetors have easy access adjustable secondary air flow. Other carburetors require special tools or removal of the carburetor to accomplish this simple adjustment.
The package is completed with high quality, light weight die-cast aluminum fuel bowls with fuel level windows for quick visual reference. Float level changes do not require removal of a sight plug with the risk of fuel spilling all over the top of your engine. Bowls come equipped with 3/8” inverted flare fuel inlet fittings and will accept all conventional dual feed fuel lines compatible with Holley four barrel carburetors.
And best of all, PROFORM’s new Street Series Carburetors are hand assembled in the U.S.
