A girlfriend back in college days had a 63 or 64 Chrysler 300 letter model. It had the 413 with the cross ram intake; got about 10 miles per gallon or a good day.
They’ve come a long way since then, haven’t they? I love the masculine grill on the 300; mine will be 3 years old in July and there isn’t a day I drive that I don’t think about what a great car it is.
