Hemi Engine Identification
By David Mizen
The engine number can be found next to the distributor.
All Valiant Hemi engines have a "D" prefix. Chrysler Centura Hemi engines have a "DF" prefix.
The second digit refers to the size
The third digit refers to the performance level
|2||Standard Performance (1 BBL)|
|3||High Performance (2 BBL)|
|4||Premium Performance (Pacer, R/T & 770)|
|5||Six Pack (E37 & E48)|
|6||Six Pack (E38 & E49)|
EDIT: Pacer and R/t models were only 70-73 hence only A, B and C motors can be pacer and R/T. 6cyl 770's also had the D34 prefix
The fourth digit refers to the gearbox type
|3||3 speed manual|
|4||4 speed manual|
The fifth character is the year of manufacture.
|DIGIT||YEAR OF MANUFACTURE|
|G||1976 pre July|
|H||1976 post July|
|...and so on...|
The remainder of the digits gives you the sequential build number.
