We need the casting code as shown in the picture below. Then we can tell you. Don't be mad yet ...
If you can give us the date code, too, great. The engine casting code will tell us. It is a raised number and will look like the example in the second image/attachment.
The engine in the picture is a 261, but the codes might be in the same place on those more modern engines. You might have to clean some crud off to read them.
