If you are having clearance issues under the hood, Holley is here to help with their line of drop-base air cleaners. An unfortunate circumstance of upgrading to a bigger carburetor is less room under the hood. These stamped steel, sixteen-inch air cleaners are designed for Holley carburated applications and feature a 15/16 inch drop base for hood clearance over Holley's standard air cleaners. Open-style filter elements are available in either classic white paper or washable and reusable red oiled gauze.
