Not an a-body but your opinion on worth...

I would buy it for $2,300... Tell him to cut you a deal because of the engine smoking, and for what you have to spend to be safe on the road, come with cash in hand. In Texas, I would buy it, fix it, clean it up, then list it as one owner truck. $3500, make a few bills on the sell, just for my time. I am just saying! Go for it!
