USAC went thru the last ten years of seven powerhouses in the field. Chances were one of the seven were going to win at just about every show, When I followed it around and worked on a crew part time there were only four full time teams and another few that would make most in the region.

If anything two or three leaving most of the races is going to allow others to compete for more than tenth.

Lets not kid ourselves, It's a hard series to win in. Qualifying is probably A number one in if your starting behind the eight ball or not.

As far as racing, Heats are by far better in USAC, Starting the two fastest outside the transfer makes for passing. Allowing a heat winner to advance his starting spot by winning makes for passing. I've seen many nights the heat winners came from the third row in three or all four of the heats.. As far as features. If there is dirty air, the racing in comparable either way. Lots of yellows, USAC is better by far..

If you see a pass between laps two and eight of a winged race and after a caution, Someone got the jump or someone messed up. Thats how much clean air means to it.
