The debut of GM's X-Body platform took place in a changeover year in naming conventions. Technically known as the Chevy II Nova in 1968, Chevrolet dropped the "Chevy II" nomenclature for 1969. The X-Body's 111-inch wheelbase made the Nova one of the smallest muscle cars to ever emerge from Detroit. With several small and big-block V8 options, the Nova packed a big punch in a small package. That still rings true, as our LS swap systems allow you to bolt in the Gen III/IV engine of your choice.
