Turn up the performance on your street machine with the 750 CFM Street Demon®. Designed for engines that demand more airflow, this carburetor keeps the same user-friendly simplicity and iconic looks that made the original a favorite among enthusiasts. It’s calibrated to deliver rock-solid idle characteristics, instant throttle response, and unmatched smoothness at cruising speed. The dual-pattern mounting flange allows easy installation on both square and spread bore manifolds, and the integrated fuel bowl design prevents leaks while reducing heat soak. Its aerospace-composite fuel bowl keeps fuel up to 20°F cooler, helping to resist vapor lock on hot days. Finished in a durable shiny coating, this 750 Street Demon is the perfect blend of form, function, and street attitude.

Features:

  • Ball burnished shiny aluminum with black composite fuel bowl
  • Designed for use on most stock to mildly modified V8s
  • Developed from the ground up with smooth styling - patented timeless design fits modern as well as traditional themed vehicles (Patent No.: US D648,746 S)
  • One piece airhorn is easy to clean and maintain
  • Electric Choke Management means easy cold starts
  • Dual mounting bolt pattern - fits most aftermarket spread/square bore intake manifolds without 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 750 CFM while maintaining the crisp throttle response delivered by small primary bores
  • Secondary air valve control with torsion spring allows smooth primary to secondary throttle transition, optimizing fuel distribution across cylinders for improved throttle response at any opening rate.
  • 2 Stage metering rods control 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
