on this website at the towards the bottom of the page, it says
T0205EG – engines for models through 1969
V0525CNR – engines for 1970-and-later models


your engine casting says the year is between 1963 to 1976 so that 6 could be 66 or 76. But the above website says 2 didgit suffix codes were 69 and earlier. So that would make your block a 1966.
The suffix code of UH I could only find in one place. Here.

And It only says UH=292 6cyl and that's on the 67=72 page. There should be more info on the UH code. Hopefully a guru will chime in.

Thanks for the info! Based on those sites it sounds like my engine is the original for the truck. The casting is June of 66 and the final config stamping is October of 66, which would be right for a 67 truck. The UH for 68 says 292 with manual, I'm guessing it probably means the same thing for 67, which is what my truck is. If I recall correctly they didn't start putting partial VIN's on the truck blocks till the early 70's, can anyone confirm that?
