I'd use the state to get a title much cheaper, you need to know the rules in OH to see if you can register it while the search is being done.
Then you would need to know the MVD rules for swapped engine etc. most likely not an issue.
Looks like an old school Kenne Bell race car, I can see why it could be abandoned owner may be dead or old etc.
Then again if there's a problem with getting a title and registration from MVD it would be on the newest owner.
