How to sell a used engine?

If you bought a motor that had a stock compression of 145 from the factory and you tested it at 100 on all eight, what would you think of that motor?
You'd think it needed a rebuild.
Of course numbers matter.

Yes, but, we don't know if it is stock compression or if it is even the stock cam........

If it was stock compression and a big cam. IT COULD be a good motor with 100 psi.

If it was me, trying to buy this combo i would bring a leak down tester, as that would tell me much more then a compression test.
