In 1978, the Monte Carlo was downsized to be more efficient and appealing to American car buyers. While performance wasn't a target at the time, a car that weighs 800 pounds less than its predecessor also carries the potential, especially when sitting on GM's new G-Body architecture. Whether your Monte has a traditional small block Chevy in it or is in need of an LS swap, we have all the bases covered.
