CHRYSLER ENGINE SERIAL NUMBER DECODER MANUALS
It seems each plant stamped engines as they saw fit, regardless of the decode guides printed in the factory parts and service manuals (and reprinted in numerous non-factory guides). Engine ID stampings began in the 1970s to get very inconsistent in format and content (and prior to the 1970s, keep in mind that Canadian-made engines have stampings almost completely different to US-built engines). Engine identification is unfortunately not so simple. This information is provided "as is" and is for information purposes only!!! Mopar Engine Block Casting Numbers casting number CID years notes

010" undersizedīelow is a listing of casting numbers for A-series, B/RB-series, LA-series, and G/RG-series enginesįor additional engine ID information for B/RB engines,see this page. Here is a short list: Symbol Descriptions These were mostly to indicate to the engine assemblers that oversize or undersize components will need to be used because a journal or bearing was machined to require it. There are many other stmapings that wound up on the ID pad or along the oil pan rail. Quite often, these stamped IDs will be followed with an E indicating a cast crank. The "T" indicates that it was made at the Trenton Plant (it does not mean truck). And not all block that wound up in high performance applications always got a block stamped HP.įor Engines made begining in 1974, the CID displacement will be prepended a "T-" Where 4T- means 1974, and 8T- mean 1978. A block might not have either an HP or an LC. Likewise, a L or LC would indicate a low compression engine. Some of these engines will be stamped with an HP indicating that it was destined for a high performance application. If a dash and three numbers follow, this indicates the date it was stamped (not necessarily cast).

If an additional three digits follow, usually after a dash, these will indicate the date it was stamped (not necessarily cast).įor Engines made begining in 1965, again the first character indicates the year for (in set order).

The Year code is followed by the first two digits of the CID displacement (ex. For 1960-1964 blocks the engine code will start with a letter year code in the set that indicates (in set order).
