No super six wasn't on any of the ram trucks. Super six only came on late 70s aspen's and stuff like that. Pretty sure it was like 1977-1979 ish stuff.
The "Super Six" (2bbl) was available from the factory on Slant-6 passenger car applications in the United States (except in California in certain years) from 1977 through 1979 and truck/van applications from 1977 through 1983. Add one year to the end of those ranges for Canada.
