The Cyclone is our lowest profile SB Chevy manifold and is also the only one that is street legal on pollution controlled vehicles. It is set up to accept a spread bore carb but comes with an adapter plate that permits the use of square bore carbs. To remain street legal with a square bore carb, you must use one that is also approved as street legal for your application. These are great all-around street manifolds for mild performance applications at affordable prices.
