Cars before 1982 are subject to a lot lower emissions standards. They just do a tailpipe test. And from talking to a few guys I know, as long as you're running on at least 4 of 6 cylinders (or only 5 of 8) you should pass it without any problems.
EDIT: I just realized you're in Ft. Collins, I'm not too familiar with the differences between Ft Collins and Denver. Sorry about that.
