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.

The GM LS engine has quickly become the high-performance standard in the performance aftermarket. Holley and Hooker have partnered together to offer the most versatile and complete LS swap kits on the market so you can install the GM LS engine into your favorite chassis! These swap kits have been engineered by Holley for a easy bolt-in engine swap where all the parts work together as a fully engineered system.
