Description: Here we have an all BRAND NEW HP style, Holley/QFT 950 squarebore (4150), 4 barrel, double pumper (mechanical secondary) carburetor professionally set up for street and strip use. This is one of my custom builds consisting of a Holley aluminum, contoured, HP style main body for maximum flow and enhanced booster signal. This carburetor is equipped with ANNULAR BOOSTERS, which are perfect for street/strip vehicles with camshafts in the 220-260 degree @ .050" lift range, or making less than 14 or so inches of vacuum at idle. Annular boosters are better at fuel atomization, which provides a wider, more usable powerband from off-idle and up. The venturi diameter is the larger 1.562", it will flow approximately 950 cfm, and is dyno-proven to 700+ horsepower. 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. Please contact me at 7 24, 523, two 947 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 for availability. It has been assembled with high-flow .110" needle & seat assemblies, 30cc pumps, #33 squirters with pink #330 racing pump cams, non-stick bowl and block gaskets, nylon bowl screw gaskets, and vent baffle. The jetting is 78 up front with a 4.5" Hg high-flow power valve, and 86 in the rear with the power valve circuit blocked. The mounting gaskets are included as shown. Here's a list of features; Holley polished lightweight aluminum main body with screw-in air bleeds. .073" 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, red anodized, billet aluminum base plate that is much stronger than a stock Holley piece. 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 bowls with sight windows that will not yellow. No more fumbling with sight plugs! Aluminum inlet fittings. Uses a standard Holley model 4150, inverted flare fuel line with 5/8"-18 flare nut. This carburetor weighs about 7 lbs., while a typical cast zinc carb weighs in at 11 to 13 lbs. I welcome all potential bidders to check my feedback. My feedback from carburetor and parts sales is 100%, and I've sold hundreds in the past few years. I am the owner/operator of a one-man shop and my carbs are built with pride one at a time. Please see my other auctions for more great deals. Thanks, Steve
