There are two generations of 258 engines. The first generation was introduced in 1971. This earlier engine has cast iron intake and exhaust manifolds with the two manifolds bolted together by 4 bolts and a gasket between. In 1981, AMC revised the 258 for lighter weight. A new block casting and fewer crankshaft counterweights were used. A new smoother exhaust manifold and aluminum intake manifold were introduced. V-belts were replaced with a serpentine belt, and a new lightweight plastic valve cover was fitted. Although these two generations have the same bellhousing and motormount attachments, and are mostly the same internally, the differences must be kept in mind when choosing used replacement parts.

The 258 can be identified by the 4th character of the engine build date code ("A", "B", "C" or "M"), stamped into the engine block below and between the number 2 and 3 spark plugs. An engine stamped with "B" is an early 258 with a 7.6:1 compression ratio. "A" and "B" are engines with 1-barrel carburetors, while "C" and "M" are 2-barrel. "M" originated in Mexico. Other codes ("E", "F", "K" and "L") are 232 engines.

The 258 used in ’87-’90 Wrangler YJs uses a computer controlled Carter BBD. It is very simlar to the 258 used in ’82-’86 CJs, but performance suffers due to emmission controls.
