Nascar did shorten races that year. For example, in the Daytona 500, the first 20 laps are listed as not scored, with the race starting on lap 21, so technically it was the Daytona 450 or 10% shortened. A quick glance indicates races were shortened at least through the first half of the year, but the second half races were full distance.
