All Aluminum Big Block Corvettes.

This isn't the orange (maybe red) car that was used by GM for the LS7/LT2 test is it (that car was reported to be a coupe)?? I was under the impression that the car was scrapped as it was a true test car. I know there might have been a few dealers installing the Can-Am blocks (McLaren engines??) in the cars (Ray Ridge Chevrolet is reported to even have made a few 1970 Chevelle LS6 cars with the aluminum 454 blocks (most likely McLaren Can Am blocks) as well)).
