Main body without air horn or K&N Stubstack?
Just like it says. I want to get some opinions. I wouldn't mind keeping the choke but, but if the power gains are substantially more using the main body without the air horn, than using a carb with a stubstack then I would rather go with that. Any ideas?

proform mainbody is usually worth 15hp or so over an otherwise restricted carb. If the motor is already overcarbed then it might not matter.

Anyone who knows anything more about the K&N stubstacks? They claim 10% increase in hp because it smooths the airflow out into the carb. I can't imagine a carb with a choke and a stubstack being as good as as a proform main body.

Its not... it might help smooth things out for carbs with a big choke horn, like a 4150/4160 Holley, but something without one, like a Proform body or Holley HP body, won't make any use of it.
