Beginning in 1964, if you checked the correct boxes when ordering an Olds F-85 or Cutlass, you could end up with the legendary 4-4-2. That meant you got a four-barrel carburetor, a four-speed manual transmission, and dual exhausts. When Oldsmobile stuffed their new 400 cubic inch engine into their A-Body in 1965, the meaning changed to 400 cubic inches, a four-barrel carb, and dual exhausts. If you want to bring your 442 into the 21st century, our A-Body LS Swap systems can do the trick.

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.
