All kinds. Time trials first. Say there were 30 cars. !6 went to the A Main, 14 to the B Main. 2 Trophy Dashes. Fastest 4 in the B Main ran the B Dash, inverted, 4 laps, for a trophy. A Dash was the fastest 4 qualifiers of the day, inverted. 4 laps, winner gets a trophy. It was a great source of pride. 4 heat races, first head waas the slowest half of the B Main field, 8 laps. Paid a little money. 2nd heat was the fastest half of the B field. Same deal, 8 laps. Paid a little money. 3rd heat was the slowest half of the A main, same deal, 4th heat was the fastest half of the A guys. Again same deal. B Mains would be like 20 laps. Winner got a choice of money or a chance to start at the tail of the A main and see what he could do there. A main was like 35 laps. Every race was inverted starts. Every track did this and the racing was great. After a while a few guys would sandbag in qualifying, trying to gain a better starting spot. This was met with promotors coming up with a rule that if you raced a lap a half second faster than you qualified you would be DQed. It really didnt happen often because guys took great pride in qualifying fast and passing cars. Hope this doesnt give you modern racers nightmares.
