Overview:

The Street Demon line of carburetors has always been known for their clean looks, ease of use and revolutionary design. This design ensures a stable idle, crisp throttle response, and smooth performance. The optimized calibration and dual mounting pattern make it Run-Ready™ for a variety of engines and vehicles. Our new Shadow Black coating wraps all of this in a sinister package to fit the vibe of today's understated build styles! All of the popular and innovative features associated with these carburetors are still in place. This means you still get the aerospace composite fuel bowl that keeps fuel up to 20° cooler, the integrated fuel bowl/main body design with all gaskets above fuel level and no plugged passages to eliminate all potential leak paths, the Goggle Valve Secondary (GVS™) throttle plate, and much more. With the Shadow Black ceramic coating, you can be sure that your car stands alone at the next race, show, or cruise-in!

Features:

  • Shadow Black ceramic coated finish acts as a protective barrier to corrosion and heat
  • Designed for use on most stock to mildly modified V8s
  • Developed from the ground up with smooth styling - patented timeless design fits modern and traditionally themed vehicles (Patent #: US D648,746 S)
  • One piece airhorn is easy to clean and maintain
  • Aero Composite fuel bowl offers significant heat insulating benefits over aluminum fuel bowls - keeps fuel up to 20º cooler for optimum performance with modern fuels
  • Electric Choke Management means easy cold starts
  • Dual mounting bolt pattern - fits most aftermarket spread or square bore intake manifolds without an adapter
  • Integrated fuel bowl/main body design with gasket above fuel level and no plugged passages to eliminate all potential leak paths
  • Small 1-11/16” primary throttle bores combined with proven Triple-Stack™ boosters deliver amazingly crisp throttle response and drivability, superior fuel atomization and improved fuel economy
  • Goggle Valve Secondary (GVS™) throttle plate (Patent # D677755) delivers over twice the air flow of the primary bores for power you can hear and feel
  • GVS™ makes total air flow of 750 CFM while maintaining the crisp throttle response delivered by small primary bores
  • Secondary air valve control - torsion spring valve control/adjustment permits seamless primary to secondary throttle response regardless of the throttle opening rate (unique contoured profile developed for better cylinder to cylinder fuel distribution)
  • 2 Stage metering rods are easily accessible without carburetor disassembly or removal
  • Single fuel inlet for simple installation
  • Integrated 700R4/200R4 transmission kickdown cable mounting location as well as Ford A/T kickdown for proper shifts
  • Patent pending mechanical design
  • 750 CFM specific calibration kit available for tuning and altitude adjustments
  • Available TPS kit allows use with 4L60 and 4L80 transmissions

Exact item ordered, quick delivery
Size: 9.5, Color: Black Polished Full Grain
I ordered these black Cole Haan penny loafers for casual wear with jeans, khakies, and even business casual with slacks and a jacket. They've always worked perfectly for these uses. The Cole Haan version is the most versatile and still meets my sophisticated look criteria. I wear a 9 1/2 M with almost all other shoes. I have found Cole Haan to run slightly wider and slightly shorter. This fit will work with thin and no socks and a little loose in width. . I'd likely order a 10 N next time. I tend to forget this but it runs consistent with me for Cole Haan. 5 stars for the shoe and service. My bad on the slightly off fit.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr
