They run that contest every September. The 68 Blue camaro "true grit" was the original 68 pro stock camaro. Same owner, he just updated it after being stored for 30 some years. That orange 69 camaro with the white stripes, is one of the chicago street racers from the neighborhood. That camaro has a "big" inch small block in it with a "ton" of spray.
I've seen him at a local track a few years back for a test and tune night, and he clicked off a couple of 8.20's and 30's shutting it off at 1000 feet. The car will solidly in the 7's, on 10.5 W's and he street races all over the country for some big cash.
He always runs it with the clock towers off, I just happen to see a few of his time tickets in his tool box.
