While many series have adopted rules that tightly define virtually every component and dimension in a racing engine, the USAC National Midget Series offers engine designers the freedom to innovate. The innovative design of the new Chevy Midget racing engine is the product of imaginative thinking and advanced technology. The USAC Midget rulebook embraces a wide range of engines that includes four- and six-cylinder powerplants, two-valve and four-valve cylinder heads, and overhead-valve, single overhead cam, and dual overhead cam valvetrain designs. However, the Chevy Midget racing engine puts a new twist on a familiar theme. The opportunity to design an all-new Chevy Midget racing engine was an invitation for some of our best and brightest engineers to create an engine within the USAC guidelines that would be competitive in both performance and cost with existing engines. In accordance with USAC rules, the Chevy Midget racing engine displaces a maximum of cubic inches and burns methanol fuel.
