If im not mistaken...this must be the car you were talking about....

As for the dry sump system....4 cars had it.
Also, when one aquired a comp 427 from the factory..they were mailed an 8 1/2 by 11 sheet which had an outline of the comp cars and questions/blank lines on the bottom so that the customer could have any paint scheme they wanted so long as they could draw it and describe it as thoroughly as possible.
Really quite cool......
I had a chance to buy one of those sheets off ebay a long time ago....the seller and i had never seen another one and i did not even know they existed. Anyway..i passed....couldnt regret it more!
Best Regards,
