SBC V8 Cyclone Non-EGR Intake Manifold – 52001

PROFESSIONAL PRODUCTS – SBC V8 Cyclone Non-EGR Intake Manifold
Performance that plays by the rules.

The Professional Products Cyclone aluminum intake manifold is the go-to choice for Small Block Chevy builders who want strong street performance without sacrificing emissions compliance. Designed for 1955–1986 SBC V8 engines, the Cyclone is our lowest-profile manifold—perfect for tight hood clearances—and the only one in our lineup street legal for pollution-controlled vehicles when paired with an approved carburetor.

Engineered as a direct bolt-on replacement for factory non-EGR manifolds, the Cyclone features a spread bore carb flange but includes an adapter plate and bushings for square bore carburetors. (To keep it street legal with a square bore, be sure to use a carburetor approved for your application.)

With an RPM range from idle to 5,500, it delivers crisp throttle response and solid mid-range power—ideal for daily driving, weekend cruising, and reliable long-haul performance.

Features:

• Fits 1955–1986 Small Block Chevy
• RPM Range: Idle to 5,500
• Lowest profile intake in the Pro Products lineup
• Street legal on pollution-controlled vehicles (with approved carb)
• Direct replacement for non-EGR manifolds

Upgrade your SBC with the Cyclone—a performance intake that’s built for the street and stays within the law.
