My dad used to do the heads for lees cars, the 67 and the 70. we had the 67 car for a couple years around 1977-78 when it was purple and last owned by cliff spalding...lee later converted the challenger to a 4-speed and ran it in *D*...I also have both cars on movie film (super 8) at sacramento raceway, still own the oil pan dad built for the 67 dodge...
