What would they be worth?

Just wondering clementine..

I'm not trying to be a dick here but have you checked into the cost of disassembling a motor by a reputable shop, having magnafluxing and sonic testing done and checking bearings, cylinder bores etc.. I don't know about US pricing but in my part of the world you are paying 100 +per hour for that kind of service. so lets be conservative and say 4-5 hours to do all these checks. That's $500 there with no guarantee that the most critical parts are any good. You take all the risk, the seller takes none and either way it costs you $500.00. If the seller wants a good price for what should be a very salable item, he should ensure the validity of the item he is selling.

A fair statement I havent had that work done in a long time. But if a checked out 340 that needs bearings and a gasket kit is worth say.....1400? and you do the legwork risking 200? and end up paying 1K. You have paid yourself $200 to do the legwork and given a guy and honest deal AND saved a 340 that possibly could end up with a worse demise. Ultimately ya, you are right, but it seems people have a real boner for these motors and I would personally take some type of calculated risk to lay my hands on one. But ultimately you are correct....risky proposition.
