I paid $800 for one that needed a total rebuild. I expect to payabout$2,000 for the machine work. If the 340 has low mileage, then $2,500 with a good trans isn't bad at all IMO.
Exactly. Its a good running motor till you put it in your car and find out its burning oil and has no compression, makes noise etc. Unless its running in a car from a reliable source I wouldnt pay $2500
