Engine Comp numbers

So I got the compression test done on an engine I'm looking at:

"Comped 100,90,100,100,100,110"


Are those pretty solid numbers?

That 90psi is a little low. Is this a dry test? If so, I'd try a wet test (put a few drops of oil in the spark plug wells).

Alright. Found another engine.

"compression average is 175 all the way accross, and had 90 pounds oil pressure cold. "

Those are probably better numbers I'd imagine?

I don't know what the oil pressure should be (and I don't have my bentley handy to look it up), but the comp numbers look good. Go for it dude!
