I've got that book somewhere also. I'll do some searching tonite. The engine that was in it when it was displayed here may not have been the same that ran 200mph because it was just an empty dummy block.
Some of us wanted to get it running and take to Toppers and Prime Steel in the mid 90's, but John refused to let us do it. I remember talking to him on the phone, but that's my only dealing with him.
Anyone who went to SSS/SCS in the 60's to early 90's always asks about it.
