That sounds about right, I think Johnson told me it was Mitchell who drifted in to the dirt bank at Atlanta.
It has a 302 in it when I bought, and had the Corvette four-wheel discs. I think the rear gearing was 4.10/4.11, and was a positraction unit. I cannot tell you whether the VIN # was still on it, or even if the engine was matching to the chassis (that car had been raced for several years before I got it, and at that, apparently in several endurance races).
While I was racing it, we blew the engine it came with, and replaced it, eventually with an Al Bartz-prepared 302, with dry sump. That was a nice motor, which made its way into a Corvette I raced and another later model Camaro.
Wish I could help with who bought the car from the broker I gave it to, to sell for me, but never knew the counterparty, all I got was cash back from the broker after the deal closed. Rumor mill had that it went to a guy in Louisiana who used it for dirt track racing, and eventually totaled it.
Thanks for the help, and information. It fills in some of the blanks.
