Verne,

Unfortunatly unlike the Mopar guys, who have long studied "pilot cars" (there is even an article in one of the current mags) Chevrolet "pilots" are un-studied. It would be neat to see if any other "pilot" cars (regardless of carline) can be found. Were you able to uncover any paperwork (engineering especially) pertaining to your Impala? I often wonder if engineering or other paperwork can be found on this LS6. I am sure since it was known by the plant to be a "pilot," that additional engineering data existed..would be a neat find and certainly would help with LS6 knowledge.
