Another optional engine was offered with two four barrel carburetors, the legendary "Duntov" cam and solid lifters. This engine produced 270hp. 1957 was the first year that Chevrolet ever offered fuel injection as an option. A engine fitted with solid lifters, the "Duntov" cam and fuel injection was rated at and cost $500. This was the first time in history that a General Motors vehicle achieved 1-hp-per-cu-in in a production vehicle. Fuel injection continued as an option throughout the early 1960s. However, most mechanics of the time didn't have the experience to keep the units running properly. This prompted most buyers to opt for conventional carburetion.
