- Here we have an all BRAND NEW, Holley/QFT 500 cfm (2300), 2 barrel carburetor professionally set up for circle track racing use. This is one of my custom builds consisting of a Holley aluminum 4412 main body. This is NOT the cheap Chinese knock-off junk sold under the brand name "Pro Comp". These parts are machined in Bowling Green, Kentucky and are first quality. THIS CARBURETOR IS LEGAL IN ALL RESTRICTED CLASSES AND WILL PASS TECH. It is essentially the same as the Holley 0-4412CT, but at a better price (Summit price is $589.99), and it is lightweight aluminum, which also has a cooling effect on the fuel. Cooler fuel can lead to a slight horsepower increase. It is also available with the gold zinc linkage and pump arm. Just ask. I have regular customers that prefer this over the Willy's 2 barrel.
Please call the number below with any questions or concerns regarding your application, and available options and pricing. I can set this carburetor up to work best with your combo. I usually have two or more in stock, just email or call 7 two 4, 5 23, two 947 for advice availability.
It has been assembled with a high-flow .110" needle & seat assembly, 30cc pump, #31 squirter with pink #330 racing pump cam, non-stick bowl and block gaskets, nylon bowl screw gaskets, and vent baffle. The jetting is 75 with a 4.5" Hg high-flow power valve. The mounting gasket is included as shown.
Here's a list of features;
Holley lightweight aluminum main body. .070" idle and .030" high speed bleeds installed.
Cast aluminum metering blocks that are custom calibrated for maximum performance.
4 corner idle for fine tuning your idle circuit.
Heavy duty cast aluminum base plate. THERE ARE NO VACUUM PORTS ON THIS BASE PLATE. IT IS DESIGNED FOR RACING USE.
Teflon coated throttle shafts, stainless steel throttle blades, and loctited button-head screws for increased flow due to decreased turbulence.
Lightweight aluminum racing style Holley fuel bowl with a sight window that will not yellow. No more fumbling with sight plugs!
Aluminum inlet fitting.
This carburetor weighs about 4-1/2 lbs., while a typical cast zinc carb weighs in at about 7 lbs.
