Description
PERFORMANCE AND RELIABILITY. The Demon 625 Street Carburetor is engineered for street-driven V8 engines, providing 625 CFM airflow with vacuum-operated secondaries. It offers smooth idle, responsive throttle transition, and strong power on demand, making it ideal for stock to mildly modified engines. This carburetor ensures consistent drivability and fuel efficiency for everyday use.
CONSTRUCTION AND APPEARANCE. Featuring a polished aluminum body with an integrated fuel bowl design, this carburetor reduces potential leak points and enhances long-term reliability. The bright, clean finish complements classic and modern engine bays, while durable aluminum construction keeps weight down and strength high.
INSTALLATION. Installation is straightforward due to its dual mounting bolt pattern and a single fuel inlet design, requiring no drilling or special adapters for many aftermarket manifolds. It bolts on easily, making it suitable for street enthusiasts seeking a hassle-free upgrade.
WARRANTY. This carburetor comes with a manufacturer’s limited 90-day warranty for added peace of mind.
APPLICATION. Fits a wide range of vehicles from 1952 through 1996 model years, suitable for most stock to mildly modified V8 engines equipped with unrestricted emissions setups. Actual fitment may vary depending on engine configuration and intake manifold compatibility.
