In 1964, Pontiac broke a GM rule by putting an engine larger than 330 cubic inches engine into a LeMans and created the muscle car as we know it today. The big 389 was good for 325 hp, 348 in Tri-Power guise. Putting big engines in little cars became the American way and gave birth to several iconic muscle cars in the 1960s and 70s. If you'd rather have a more modern powerplant under the hood, our A-Body LS swap systems have you covered.
