ABOUT THIS PRODUCT

WICKED POWER! The all-new Street Demon redefines what a true street carburetor should be - clean looks, smooth drivability, and power on demand. Engineered for easy installation and everyday performance, the Street Demon features a revolutionary design that combines stable idle quality, crisp throttle response, and seamless transition from cruise to wide-open throttle. Its dual mounting pattern and optimized calibration make it Run-Ready for a wide range of engines, from mild small-blocks to stout big-blocks. The patented Goggle Valve Secondary (GVS) design delivers quick airflow when you need it most, while the integrated fuel bowl and main body eliminate external leak paths for long-term reliability. Finished in a bright, shiny coating that complements any classic or modern engine bay, this 625 CFM Street Demon is ready to bolt on and drive.

Product Features:
  • Ball burnished shiny aluminum finish
  • 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
  • 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

  • Goggle Valve Secondary (GVS) throttle plate (Patent No: D677755) 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
  • 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.

  • Single fuel inlet for simple installation
