Stop in for a cup of coffee

I found 2 on Ebay and they are priced at $600. That is unrealistic to me and was thinking $250 to start. I am actually selling it for a friend
I had a 4 barrel Offy intake on my Land Cruiser, was there when I bought the rig but priced it (2F straight 6), they were $400-600 years ago but everything seemed to cost a lot for it
