To be historically correct, one of the first rear engine cars at the speedway was the Gulf Millers from 1938 and the 1949 Rounds Rocket was rear engine. I am sure there may have been a few more but these come to mind.[/QUOTE] I have a strong feeling you knew where I was coming from with my comment but knock yourself out with the correction. Deucemac, on the other hand, got me dead to right. With my comment I had only taken the '63 second place Lotus of Jim Clarke into consideration even though I knew of Brabbham's Cooper. I admit to not being a student of the 500. Real sanctioned, competitive, professional series' will never revert no matter what type of racing it is.
