Kerry's got it right, if you haven't heard it run, done a compression check, checked the oil pressure, leak down test, pass.
Very recently someone on another board bought a rebuilt 235 that supposedly had been run and broken, and left to sit for 7 years. It was sold for almost the price of a rebuilt. When the head was pulled off there was a score down one cylinder and no honing or cross hatching to be seen. When the crank was pulled the bearings looked to be run with out oil.
I bought a truck for the 292, supposedly only had about 10k on a rebuild. I did a compression check and when cylinder was out of spec with others. I pulled the head and there was a score down cylinder an inch wide. The piston looked great, no problems with rings, nothing wrong. Best guess they didn't bother to bore the cylinder to remove the score when they rebuilt it.
Again if you can't verify the condition of the motor, it's only worth core value.
btw you should be able drop any 230 into your truck. When I first started working a gas station too many years ago, I put a 59 in a 38 truck. There were no major problems.
