I would avoid the '83 250. With the integral head it doesn't have much performance upgradability, and it only makes about 150 hp, which a healthy 235 can match, as can a stock 261.
Let me put it this way:
I had a '67 stock 250 in good condition sitting in my garage that I got for free. I traded it for a 261 that slightly smokes but otherwise runs great, and I feel like I got a good deal.
