Good morning,

That block code was used from 1974- 1987- they were typically used in trucks. I have one myself that I pulled out of a 1981 motorhome and stuffed it in my chevelle.

It's a good solid block. When you say compression do you mean the compression ratio, or do you want to know what good compression should be when compression testing?
