WICKED POWER! The ALL NEW Street Demon™ redefines the street four barrel  carburetor with clean looks and ease of use! The Street Demon offers enthusiasts a straightforward carburetor designed to deliver a stable idle, amazingly crisp throttle response and smooth performance. Its optimized calibration and dual mounting pattern make it Run–Ready™ for a large variety of engines and vehicles!

  • 625 CFM air flow - ideal for use on most stock to mildly modified V8s
  • Dual mounting bolt pattern - fits any street 4bbl intake (square flange or spread bore)
  • Electric Choke Management means easy cold starts
  • Single fuel inlet for simple installation
  • Aerospace Composite fuel bowl offers significant heat insulating benefits over aluminum fuel bowl - keeps fuel up to 20º cooler for optimum performance with modern fuels
  • Integrated fuel bowl/main body design with gasket above fuel level and no plugged passages to eliminate all potential leak paths
  • Small 1-3/8” 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 delivers over twice the air flow of the primary bores for power you can hear and feel
  • GVS™ makes total air flow 625 CFM while maintaining the crisp throttle response delivered by small primary bores
