Engine Identification
How do I identify my engine cast number?
There are many existing pages to identify your engine. We’ll attempt to provide the best of them to you, rather than recreate the information here.
Inline (6 cyl) Engines
To determine the year of 235 or 216 engines, look just above the starter on 235 or maybe remove starter on 216 and there will be a letter followed by 2 or 3 numbers. The letter stands for the month, the next one to two digits are the day of the month and the last is the year.
Example: A239 if its is a 235 means Jan 23 1959, if its a 216 it would be Jan 23 1949. I like 54 because its water pump is the right height and length and its easier to disguise as a 216 with a 216 valvecover.
V-8 (8 cyl) Engines
Here are some links to help you identify V8 casting numbers.
