AMC 304
V8
Once AMC bought the Kaiser Jeep Company the CJ engine compartment was lengthened 3 inches to accommodate the six and 8 cylinder engines. The AMC 304 V8 was used as an option in CJs from 1972 to 1981.
The AMC 304 was the only V8 used in any CJ but all the AMC V8s such as the 304, 360, 390 and 401 use the same engine block. The only difference is the bore and stoke. The accessories will all bolt up the same. The transmission and engine mounts are the same. This makes swapping out the AMC 304 in favor for another AMC V8 easy.
