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.

From Ford Flathead to GM Gen V LT, and including everything in between like small-block and big-block Ford and Chevy, Gen III/IV LS, Coyote, Hemi, and more, we have the parts to coax more power out of the engine under the hood of your hot rod.
