I haven't put a bore guage on it yet(don't have one yet) but like dad says, "what else do you think the 080 could stand for?"

i don't think a stock block can even be bored over that much. Could it be sombody was getting creative with a set of punches

or mistakenly grabbed an "8" punch, thinking it was "3".
i have seen stock blocks taken to 4.090" and i have taken one to 4.185" accidentally myself. never cut into a water jacket. sleeved it and ran it. BTW, it was my first bore ever, and i must've slipped when i was setting it up. by the time i realized what was wrong, it was too late to stop. ended up sleeving it and calling it good.

If that is an 80 over piston, then kiss that block goodbye!!!

Last month when I picked up my 350 block from the machine shop (I had it bored .040 over) I asked what the max over bore was. The head machinist told me that they had done several .080 over without any problems. He said he couldn't do it for a 400 but 350's were no problem.

I can't believe it could be bored 80 over and not use block filler of some sort. If it is then really 80 over its gonna run warm either way, filled or not.
Please measure it, Enquiring minds want to know.

Yeah, on my bone stock 010 block it had 6 pistons that said that. The other two said nothing. There is no overbore in the block.

Did you end up finding out? 
When I got my short block from City Motor Supply last year it had the same pistons in it. My cousin(a mechanic) said that it did mean it was bored 80 over and to watch for overheating and running hot. But, I haven't had any problems with it yet. Don't know if I'm just lucky or what though.
