The Chrysler Slant Six is one of Uncle Tony’s favorite engines. He’s built a wide variety of engines over the years, yet he keeps coming back to the cast-iron cooking pan simplicity of Chrysler’s legendarily indestructible six. He’s even gone to the trouble of wrapping one in a Swiss-cheesed Dodge Dart that has had every last unneeded ounce of weight shaved off. We saw that car, we heard that car…and we were told that he was planning on building a “real” engine for the Dart when he could get around to it. Apparently, that time is now, in-between building a customer’s car and the Bottle Rocket Coronet, just as the Kentucky/Tennessee area gets it’s ass handed to it by Jack Frost himself.
