Welcome to the Bolt Squeegebob.

Here is the "overexplanation" of what everyone else said if you wonder where you could find the info yourself.

These two sites should tell you what you need to know. Look under 1954 - 1957 Engines on the first page and you will see an example and explanation of how your engine number is laid out. You won't find the "XA" explained on this page.

This second site provided by one of our site sponsors gives the XA definition. Put "1954" in the Engine Code menu.
