With the muscle car era in full swing, the 4th Generation Dart began production in 1967 and immediately got in on the fun. Range-topping engines included 340 and 360-cubic-inch small blocks as well as 383 and 440-cubic-inch big blocks. Hemi 426 power was even made an option in 1968. If none of those get your attention, it might be time to drop in a Gen III Hemi with one of our swap kits.

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.
