Known for its deep Quadrajet expertise, Cliff’s High Performance helps vintage-GM enthusiasts bring original carburetors back to dependable street and track service. The Mount Vernon, Ohio, shop builds application-specific rebuild kits and tunes carburetors around each customer’s vehicle rather than treating every unit as an off-the-shelf job.
British SuperiorFounded in 2002 by British-car specialist and former Navy-certified aircraft mechanic Joe Curto, British Superior makes parts and rebuild kits for vintage S.U. and Zenith Stromberg carburetors while restoring the carburetors themselves. Curto built the business from repairing British sports cars in his parents’ Queens Village garage, carrying forward patterns and molds from Salcorp, a longtime supplier to Beck-Arnley and Moss Motors. Most of the company’s products are manufactured and assembled in the United States, with machine work available for worn bushings and throttle shafts.FLUSHING, NY
