SBC V8 Cyclone Non-EGR Intake Manifold

Cyclone Intake Manifold – Low Profile. Street Legal. All Performance.

The Pro Products Cyclone intake manifold is the perfect choice for builders who want reliable street performance while staying emissions compliant. Designed for 1955–1986 Small Block Chevy engines, this is the lowest-profile manifold in our lineup—and the only one that’s street legal for pollution-controlled vehicles when used with approved components.

Engineered as a direct replacement for factory non-EGR manifolds, the Cyclone accepts a spread bore carburetor but includes a special adapter plate and bushings to run a square bore carb as well. To remain street legal with a square bore, be sure to use a model approved for your application.

With a powerband from idle to 5,500 RPM, the Cyclone delivers great throttle response and strong street performance across the rev range—perfect for daily drivers and weekend cruisers alike.
