Somewhere between the Ford GT40 and the much-mocked Pontiac Fiero sits a 1965 Chevrolet Corvair that owner Chuck Rust turned into a mid-engine V8 sports car using the little-known “Crown” conversion kit. Builders who attempted this exact swap decades ago describe cracked differentials, hand-fabricated input shafts, and a kit that solved only the easy part of the problem. With a claimed pedigree that traces back to Smokey Yunick’s praise for a properly sorted Corvair, this homebuilt project asks what America’s mid-engine sports car could have been.
