Personally, I would throw that (or any other Hhhholley) carb to a drag racer!
Find yourself a Rochester Quadra-jet. If you have to, buy a spacer/adapter.
Then as previously posted buy gas without ethanol.

I'll probably get scolded for saying that about Holley carbs, but in my experience, I've always had good luck with Rochester carbs.
