Seems to me I remember one of the insiders at Lansing (Marty, maybe??) talking about a one-off with the Z06 LS7 engine in it.
Wonder if that will every show up at an auction. I'd try to beat Doug Allen to that one.!!!
Rumors at the time were that the Final Production scheduled for the 08 model year would run LS7s. Too bad those never made it to the street.
