Beginning in 1992 for the 230hp 5.2L and 1993 for the 245hp 5.9L, Mopar engines were redesigned and given the moniker, Magnum. With great cylinder heads, multiport injection, roller camshafts, and a bellhousing pattern that can easily be mated to many Jeep transmissions, they’re a natural swap for Wranglers. We spied this 5.2L Magnum complete from throttle-body to oil pan. Check the side of the block under the exhaust manifolds for the casting numbers. The 318 engine will end in “318” and the 360s will end in “360.” Easy, huh?
