350 SBC Chevy Long Block

Purchased for a project and decided to go another route.

The heads appear to have never been ran. The short block I believe has. No ridge and can see cross hatch with no scoring or wear that I can tell. Previous owner thought it only had a few hours run time. I would like to get my money back out of these parts and I paid $1000. Located in south Bismarck.
