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?

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.
