Holley (qft) Hp 650 Cfm High Performance Street/strip, Vacuum Secondary, 4150 on 2040-parts.com
Jeannette, Pennsylvania, US
Here we have a Quick Fuel Technology 650 cfm squarebore, 4 barrel, HP vacuum secondary carburetor professionally and set up for street and strip use. This carb employs the modern universal linkage, QFT polished aluminum HP main body for added flow and enhanced booster signal, high performance downleg boosters, red anodized billet QFT metering blocks (model 4150), and 4 corner idle. It will flow 700+ cfm and will easily support 425 horsepower. Please call the number below with any questions or concerns regarding your application.
It has been assembled with high-flow .110" needle & seat assemblies, 30cc pump, and # 28 squirter. The jetting is 69 up front with a 6.5" Hg high-flow power valve, and 77 in the rear with the power valve circuit blocked. I've installed an adjustable secondary cover for easy secondary opening rate changes (purple spring installed). You just turn the screw on the side counter-clockwise for a quicker opening rate, clockwise for slower. It was assembled with a new heavy-duty cast aluminum QFT base plate, new polished aluminum bowls with clear, non-yellowing sight windows (no more fumbling with brass sight plugs!), new screws, jets, blue non-stick gaskets, and the mounting gaskets are included as shown. THIS CARB WAS DYNO-TESTED ON A MODERATEY BUILT 355 and made 423 horsepower, therefore it is not exactly new, but good as new.
Please email or call me at my shop with any questions regarding fitment. I'll need your engine, trans (stall if automatic), and rear gear specs. I can be reached at 724-523-2947 from 9 am 'til 7 pm, eastern standard time.
I welcome all potential bidders to check my feedback. My feedback from carburetor 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

2014 Hyundai Genesis first glimpse
Thu, 24 Oct 2013Here are the first official shots of the next Hyundai Genesis, a long, cool drink of water that will chart the course for many larger Hyundai sedans to come. “We want more premium luxury,” said Moon Sik Kwon, president of Hyundai R&D. “Genesis will lead the way.” Details are not officially released yet, so, even though we just drove the thing all over Hyundai's Nam Yang proving ground here in Korea and have a definite opinion about it, we can't tell you whether or not it was a well-composed, powerfully quick, huge step up and over the first Genesis sedan.
