Better make sure your taillights are working, because that's all your competition will see when you drop in a Mopar Performance 402 Magnum Crate Engine. This 4.00" stroker engine generates a whopping 435 horsepower and 457 ft.-Ibs. of torque at 4500 rpm, and will make believers out of everyone in a hurry. The 402 Magnum features big valve Magnum R/T cylinder heads and stainless steel valves. Drop one in and let 'er rip. For maximum performance, Mopar Performance recommends the use of a 750 cfm Holley Carburetor (P4349228 - available through Mopar) and 1 7/8" Exhaust Headers (not available through Mopar).

Crate engines that change the emissions performance of the vehicle may not be legal for use on vehicles regulated for highway use in California and other states. Horsepower and torque rating based on test engine. Ratings may vary on individual engines.
