390 or 352

Hi drcota, welcome to FTE!
The 352, 360, and 390 all share the same block. All 3 could have the "352" number cast into the front of the block.
I think one of the easiest way to tell for sure is to remove one of the plugs, and check the stroke.
Here's a thread from the '61-'66 forum with more details:
