Motown Engines

We've got an engine with more cubic inches of displacement over the original 426, translating to an abundance of torque. Based on the WORLD PRODUCTS 426H aluminum block, it's superior to OEM in many ways and topped off with a pair of deep-breathing aluminum heads and forged rotating assembly consisting of a forged steel 4340 crank and rods, plus a set of forged pistons. They are available exclusively thru our Engine Builder Program.
