21 cars (20 taking time and starting the race) is not a good sign for this series. The 5, 37, 43, 56, 50 weren't there from 2011 (among others I can't think of). There were two additional cars there this year (7 and 141) and yet there was still a loss of cars. Sad that this series has fallen so far but I completely side with the small owners of Silver Crown cars. They don't have massive R&D budgets to convert over to ethanol. As evidenced today, one car burned a piston and multiple engine overheating are only going to continue to plague this series until things change. Those changes are needed fast before this series is gone.
