Description
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.
