Umm... a 230 out of a forklift?
If that's a 23" block, which it should be as a 230, I'd snag that and use it. Don't take the crank out, use the whole engine.
For one, to run on LPG it would probably have had hard valve seats installed. Cool... will live with unleaded fuel. Also it's all matched up, crank and block, ready to go. Go through the regular rebuild routine with it and you're away.
