That race, like many/most USAC shows I attended in the 60's and early 70's was on a Sunday afternoon. While the racing was some of the best I've ever seen, those sunny afternoon deals didn't help a lot in producing tacky super fast surfaces.
I'll have to do a little research. I don't recall exactly when they went from the 305 c.i.d.'s to 410's and from the skinny tires to the big wide rear tires (mac miller calls them cartoon tires

), but of course those new specs resulted in lower TR's when they were introduced as well.
In the 60's there had to be ideal conditions before we would see sub 18sec. laps at the Big "E" on a Sunday afternoon. That said, you just had to be there to believe the racing provided by Foyt, B. Unser, Branson, McCluskey, Larson, et al and of course Hurtubise.
