2bbl and 4bbl Distributors?

What's the difference? if you set-up a Dizzy on a machine for a 4bbl
and drop it into a 2bbl car what will happen?
I just got my rebuilt dizzy from a member here. I mentioned at least 3 times in our conversation that it was a 273 2-bbl.
It came with a full Report Card of all the Testing done. (Very Professional like)
It say's 273-4 All over the paperwork tho...
Should I drop it in?
