440 block question on pricing

A guy local to me has a 440 block says it's a 67 non hp. He's taking offers what should I offer him. Block is bare, I haven't seen it. He lives around the corner from work so its not like I'm going out if my way to see it. Thanks

bare block, no more than 2-3 hundred. I got a complete 440 out of a 73 charger for 200, complete, running in November 2014.......
