I have four A3 motors in various states of completion.
One is pretty much 100%, complete w/cylinder and head, I've never heard it run but it has good compression and turns over nicely.
I have two complete bottom ends as well, one looks pretty good, the other is kinda ehhh.
Then I also have one complete but 100% disassembled motor with some rare parts (NOS crankshaft, nice case & bearings, etc)
I'd do 125 shipped for the nice complete one, 80 for the better of the two bottom ends, 60 for the not as nice one, and would take offers on any of the spare stuff I have. Or take EVERYTHING (enough to build 4 motors) for 300 shipped to your door.
