With the muscle car era in full swing, the 3rd Generation Valiant and Scamp began production in 1967 and immediately got in on the fun. Range-topping engines included 273 and 318-cubic-inch small blocks. If none of those get your attention, it might be time to drop in a Gen III Hemi with one of our swap kits.
