Ex-GM, that would be Kinsler's car, correct?
Thus the "intake stacks" are not from FAV but rather Kinsler's own design (when you make injection systems on the side from your GM engineering job, you just might find time to whip up a system for your GT40!).
Glad he was able to buy it from GM and it didn't get the usual "engineering mule/comparison" car fate of a crusher ride at Warhoops! But then agian a LOT of GM stuff that was "supposed to be" crushed has ended up in private colections over the years!
