GM's 4th Generation pickup was built on the GMT400 platform and available with multiple versions of the ubiquitous small-block V8. From 1990-94, GM offered a cult legend, the 454 SS. Whether you needed to haul a trailer, get off the grid, or rip down the 1320, GM had a C/K1500 for you. But if you want to bring that OBS into the 21st century, Holley has all of the parts to make dropping in a Gen III/IV LS engine a bolt-in affair!

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.
