It looks like you bought the engine I found for you from half way across the country?!?
Good, I hope it works out for you. It looks promising. The ARP bolts are a good sign. Pull the timing cover and let's see what type of chain they used and how tight it is? I see a good crosshatch in the cylinder shown and what looks like a flat top piston? Hard to tell. Pull the oil pan and use some Plastigauge to check clearances and show us the bearings. Hopefully the temp disc thing that RRR pointed out happened before the engine was rebuilt and never replaced.
How much did you end up paying for it and what all did he throw in? We all love a good Craigslist score even if we're half way across the country!
