This was the first year the Trans Am class participated. The Camaro Z28 came in 1st & 2nd in class and 3rd & 4th overall. Great racing with Porsche, GT40, Corvette, Lola T70 & Turbin ..... Chris Economaki was amazing interviewer and his interviews with Roger Penske and Mark Donohue are very insightful and priceless.
When someone asks why Camaro Z28s are so popular and valuable even though they produced over 20,000... for me the answer is simple, it's their dominate/sucessful racing history of the first generation cars.
