I would insist on some moe detailed photos and copies of the rebuild receipts before spending anywhere near that amount of money on somebody else's rebuilt engine. It's priced at least twice as much as a normal rebuild, and all that chrome doesn't make it run a bit better! What do you intend to do with the engine once you have it in hand?
A well-built 235 without any radical modifications should cost somewhere in the neighborhood of $2,000.00 (US) and give the rebuilder a reasonable profit. Shipping would be extra, obviously. I've got a friend in New Zealand who wants me to visit him and assemble a spare engine for his 1924 Dodge truck while I'm there. He's offering free room and board, and some excellent hunting and fishing opportunities as an added incentive if I decide to take him up on his invitation! It's pretty tempting, particularly since I'm due to retire from the public school system in a couple of months!
