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?

As delivered from the factory, each distributor is set up for how the engine is equipped and what it runs in and so on and so forth. This is important during the emissions years and deeper into those years the more important it becomes for a proper running engine while passing the emissions test.

Now! The probable more aggressive curve in that (your) distributor will only help performance and probably mileage. (Good probability!) what an engine likes for more power and mileage, emissions testing/passing doesn’t like.

A more aggressive curve will only serve you better.
I’d drop that right in and go.
