To me, the winner will be the first one to realize they need to go back to the good old days of muscle cars and stuff an old-school torque monster with some modern updates in it. At least for me that is. Not that I am against doing the mods myself, got plenty of mechanical skill under my belt. But to pay as much as they are asking for them, they need to have it done already.
Just imagine a bored out 440 reminiscent of the 6 pack or the dual quad but instead of normally aspirated, something in modern injection stuff in the new Challenger. Sadly, it would twist the car into a pretzel knowing how they make stuff today. Or just stuff in
one of these (preferably the largest possible) and be done with it.
They are both great. I'll buy both when I win the lotto. (Won't ever happen cause "You can't win it, if you ain't in it.")
