Would a lost and found thread be of use here?

I think that would be great. Post the user name along with the vin number. Maybe a quick sentence giving info like "1971 340 vin 1******* found in 70 purple  challenger in western canada in 1998" then it gives people a idea of where it came from. It would help if you knew the location and type of car your original motor was in if you were searching for it. How many times have we heard " I sold my motor and the guy in this area put it in this car. "

I think keeping this to just ebody is the right thing to do. Keep it simple

I agree
