Hello and happy holidays. We currently have a 1971 Demon which we purchased from the original owners family. It had 5800 on the odo so I assumed that it had gone around once. It had a 318 and is b3 blue. After finding a correct 340 /727 I had everything rebuilt and sold the original stuff. When I started on the car itself I discovered my error. It has 5800 original miles and was just dirty from the years of storage. The restoration has stalled while I try to get the stuff back. It is an outstanding car and we are hoping for the best in the new year. Same to all of you. A1
