What is the suffix code?
Passenger side, deck surface, behind where the alternator usually sits. It should be a two or three letter code (typical) in amongst a few other stamped in numbers. You can post all of them as stamped and it's easy to pick out the suffix.
This is the ONLY thing that will tell you what the motor originally was installed in. HP, year, etc. Very rarely did GM recycle these numbers, so they are quite accurate.
Obviously a rebuild would mean the code isn't that useful, and if the block has been decked, there will be no numbers there at all. But it is interesting to me to know what the engines donor was.
Post that up, and if you've seen yet, whether two or four bolt.

i'm also very interested in it's donor, i just bought the engine from the dealership i work for for $50, the only reason the owner replaced it is b/c it burned a little oil, but that's all i know about the engine

Of course...just when you talk good about suffix codes, this one doesn't match up

That's what I use, but "UKA" from what you posted, shows as a 1981 block. Obviously not correct. They did "recycle" codes (fairly rarely), so it could be that yours is new enough that it hasn't been added.
Post whether its two or four bolt when you find out.
