I am a new 240Z owner. I have a running motor and auto trans from a 1971 Z that I want to sell. I realize that it is hard to say what a motor is worth without seeing it but could someone give me an idea of what it might be worth?? It runs well, and has 130,000 original miles on it.

A used 240 motor doesn't have a lot going for it, especially if it has been removed from a car. It is easiest to sell if the new owner can drive it and see how it runs. In my opinion, once it is taken out it is basically a core. I mean, I wouldn't go through all the work to put it in my car just to find out there is a problem and then take it out again. I would rather take it appart and check it over first and at least replace the bearings and the rings.

A 240Z motor is most valuable with the matching serial number 240Z car. Second most valuable place is with a racer that is restricted to original engine specifications. But a motor is expensive to ship so it limits you to mostly local sales. If someone is going to swap to a different non-original motor they may as well go with a 280Z, 280ZX or 280ZX turbo motor. It is hard to beat cubic inches or turbo if you want a little more bang for the buck.

I just recently gave away a L24 because I had it for sale for several years and got no takers. But there are a lot of Z's here in California. So where you are they may have more value!?

The bottom line is if you have time you have a better chance of finding someone that will pay what you think it is worth.

This is just my opinion! Sorry, I probably didn't help much.
