Styled and calibrated for Street Rods and mildly modified Street Machines and light trucks, the Road Demon™ is an impressive performer. With a remarkably smooth choke tower design, vacuum secondaries and patented air entries, the Road Demon™ offers extremely smooth operation with strong throttle response. The Road Demon™ has the standard Demon carburetor features: Max-Density Cast metering-blocks with adjustable jets and four-corner idle, a billet baseplate, plus large capacity fuel bowls with patented sight glasses for tuning ease.

The Road Demon™ 625 targets mild performance engines from 302 to 400 cid, and rated at 250-350 horsepower. The Road Demon™ 725 is perfect for stock V8 engines from 350 to 500 cubic inches. This makes them ideal for daily drivers as well as weekend cruising for a wide range of vehicles.
