I am not in the position to bore this engine, as I say I have several 292's already. I just want to get this one going for a guy who has some old junkers he wants to selll but wants a running engine in them, they are not really worth wasting my 292 stuff on.

If the pits are only in the tops of the pistons, it probably won't hurt anything to run them for your intended use.  If you really think you need other pistons, I probably have some used ones in my stash, and I don't think they are made of gold.

Thanks Hoosier, after looking at these closer, I may just run them. If I can't I may be asking you for a couple.

On another note, I think I found why it was rebuilt and never run, the Oil rings appear to be too large and was binding the rings. on the first piston I cleaned and reinstalled the rings I could not get the rings to compress down flush with the piston so on the first one I took some tin snips and cut one hump off and they fit much better. I am wondering if the set they used was for a 292, maybe the set was mixed up when bought and the engine ended up too tight and thats why it never run. The other funky thing about this set is it has an expander ring in the second groove under that ring along with having a thin ring above the top ring. anybody know what type of set this is.

The thin ring above the top ring is probably a repair for a worn top groove.  I used to do that at NAPA about 30 years ago.  There was a hand operated cutter that would cut the groove wider and square it up, then the spacer was installed above the ring.  I doubt if anyone does this anymore.  I have seen ring sets with the expander under the second ring, can't remember the manufacturer.  Pedrick maybe.

The pistons were also knurled and even without rings they appear too tight for the bores and I honed the bores quite a bit to get them cleaned up. I think the thing was just too tight when they put it back together and never got it running. There were other strange things on this engine I have never seen, originally a car block, it had a truck bell, a front mount I have never seen and a water pump pully about 10" in diameter with lightening holes in it, a 90 degree oil filter adapter and a car pan. I think they built it for a struggle buggy or something. There was no sludge in the block or heads so I know they never got it running after the rebuild. I hope I have better luck.

Put it together Pits and all, as John said, for its intention there was no sense in investing much in it.
