Product Details
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
- Aerospace 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
