This doesn't answer the question but, my first experience at Indy as a 10 yr old boy was watching Dave McDonald and Eddie parish before my very eyes in Stand J in 1964. It was an unbelievable event! I haven't missed a 500 since. That was the first year for the DOHC Fords and when they came around for the first lap with Clark leading the guy behind me screamed, "my God, look how fast they're going!!!". It was absolutely incredible. I'll never forget that day until I draw my last breath.
