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 inChevrolettive 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 degrees 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 heatDesigned for use on most stock to mildly modified V8sDeveloped 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 maintainAerospace Composite fuel bowl offers significant heat insulating benefits over aluminum fuel bowls - keeps fuel up to 20 degrees cooler for optimum performance with modern fuelsElectric Choke Management means easy cold startsDual mounting bolt pattern - fits most aftermarket spread or square bore intake manifolds without an adapterIntegrated fuel bowl/main body design with gasket above fuel level and no plugged passages to eliminate all potential leak pathsSmall 1-3/8 inch (625 cfm) primary throttle bores combined with proven Triple-Stack boosters deliver amazingly crisp throttle response and drivability, superior fuel atomization, and improved fuel economyGoggle Valve Secondary (GVS) throttle plate (Patent # D677755) delivers over twice the air flow of the primary bores for power you can hear and feelGVS makes total air flow of 625 CFM while maintaining the crisp throttle response delivered by small primary boresSecondary 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 removalSingle fuel inlet for simple installationIntegrated 700R4/200R4 transmission kickdown cable mounting location as well as Ford A/T kickdown for proper shiftsPatent pending mechanical design625 CFM specific calibration kit available for tuning and altitude adjustmentsAvailable TPS kit allows use with 4L60 and 4L80 transmissions
