in 1973 and 1974, there were two races per event: a "Sprint Race" and a "Cup Race".
The qualification times made the starting line for the Sprint Race, but AFAIK, the race that counts for the Championship was the Cup Race.
Can someone tell me how does that worked? What was the purpose of the Sprint Race; it was a no points race? And how was the grids for the Cup Race made? With the finishing order of the Sprints?

The two heat format was handled in different ways. Most tracks ran a shorter sprint race as a qualifier for the main, with the starting grid for the main usually based on the finishing order of the sprint. Non finishers in the sprint were added to the main, but usually at the back of the grid. Points were only given in the main, but the prize money was usually allocated to both events, with the majority being paid for the main.
Usually the sprint was at a lesser distance than the main. For example, 75 miles for the sprint and 125 miles for the main, retaining at least a semblance of the former 200 mile distance.
Road Atlanta in 1973, for one, utilized a format where they ran 100 miles on Saturday, with the Sunday 100 miles considered a continuation of Saturday's race.
Road America ran both the sprint and the main at 100 miles each in 1973.
The 'energy crisis' of 1974 saw a reduction of length in the races, generally by about 10%. For example, in 1974 the Road America round saw the sprint run at a distance of 68 miles and the main at 112 miles.
I am sure that Pete Lyons can give a more definitive ( and probably more accurate) analysis of this, and hopefully he will chime in here.

One reason for that split into two races I heard or read about was also the thirst of the Porsche 917 turbo 'Panzer'. I have no idea if that is true or not.
From the safety view it makes sense because in order to finish a 200 mile distance they had to carry about 200 (US)gallons of fuel aboard.

I wasn't even around to ever hear before that great line about "CanAm began with lots of cars and hardly any rules, and it finished with lots of rules and hardly any cars." Wish I'd said that!
