While reviewing some of my old picture taken at the 2011 EFV-8C/A's Auburn, IN Meet, I came across this picture of Mark Kirby's 34 coupe test vehicle that had a running sample of one of his prototype "new block" engines installed. Seems to me he said he had somewhere between 40-60k miles on this engine at that time.
stay tuned....I thought this picture was filed in my tablet, but it must be in my computer files. Will add it to this post later today
