#Throwback Thursday: 1978 IROC at Michigan

The legendary names assembled in the photo represent Formula 1, Indy car, stock car, and sports car racing, and represent countless championship and victories in their chosen disciplines.

To think they gathered to flog Camaros around Michigan International Speedway in 1978...tells of a different time when motor racing was as much entertainment as it was competition.

Rather than name all of the drivers in the group photo, try your hand at picking them out in the comments section below, and if you want to take it to the next level, try adding in their total number of championships and major event victories (Indy 500, Daytona 500, 24 Hours of Le Mans) to give context to their combined greatness.
