HOLLEY, QFT 850 HP DOUBLE PUMPER, ALL ALUMINUM, STREET, STRIP, HEAVY-DUTY BASE

Description: Here we have an all BRAND NEW HP style, QFT 850 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 new Quick Fuel Technology aluminum, contoured, HP style main body for maximum flow and enhanced booster signal. It is dyno-proven to 600 horsepower depending on your engine setup. 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 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 7two4, 523, two947 for availability. It has been assembled with high-flow .110" needle & seat assemblies, 30cc pumps, #31 squirters with pink #330 racing pump cams, non-stick bowl and block gaskets, nylon bowl screw gaskets, and vent baffle. The jetting is 74 up front with a 4.5" Hg high-flow power valve, and 82 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. .072" 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 baseplate 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 just over 7 lbs., while a typical cast zinc carb weighs in at 11 to 13 lbs. Please email or call me at my shop with any questions, as I will be glad to help you with your setup. I can be reached at (7 24, 5 two3, 2947) from 9 am 'til 7 pm, eastern standard time for tech or service help. 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.
