Not a perfect world, each has it's + and - Eddy decent carb all around take less messing with, but I think one on one performance the Holly wins. The nascar fans I am sure have noticed the absence of eddy on the top of those hotrods.

The Holly not so keen on the bowls, those need constant attention cause they always seem to ooze gas around the screws, not a big deal just sloppy looking, and not a real reason to not run them.

Then there is the Demon, that in their paper work they tell the owner to clean out the ports around the carb top regularly. Then my favorite the Predator animal carb. No matter what brand you run you need to fine tune them to get the most out of them.

As most know sooner or later they come to the conclusion, that bolts right on is a myth or industry inside joke.
BTW it takes a real man to run a manual choke ..... LOL!
