Rare 1967 Mr. Norm's 383 4 speed dart

The article posted by yellowdartdave from the February 1967 Car Craft states Chrysler announced the Barracuda would get the 383 because they felt it would compete more strongly against the Mustang.
Mr. Norm took a 67 Dart GT with a 6 and an auto and put a 383 in it with hand built headers before Chrysler had a chance to build a 383 Barracuda.
