Here is a link to the 917 engine Carl Thompson had put together for the 917 he built from the frame that was found loooooooong after it was displayed in an auto show in Switzerland or somewhere close. There is a complete build up of the whole car on another site. I was lucky enough to be at Willow Springs when it was test run for the first time in it's life.

Sets of images like this make a great background for some music by Enya or other relaxing music and have a two or three hour slide show.
