The wheels appear to be '70's vintage Corvette, is the front subframe the same? If so, I assume the motor is one of those 180 odd horse things. I drove a buddy's '79, but it was nothing compared to the '67 427 4 speed coupe I drove.
I may go look at the sale, but it's a bit a of a drive. If I do, I will see what it has for rear suspension.
