Over the past few years I've been making changes to my car to hopefully get it up to Factory Appearing Stock Tire rules eventually.

I'm starting to mess with my stock intake and I'm questioning if I should leave an intake divider in it or just open the whole upper plenum up?

The intake is a 69 2806301 for a 383. In stock form it has a 4 hole opening for the carb which I've already started to remove but, I could leave a divider in it.

My personal opinion is that the extra plenum volume would most likely be more beneficial than the divider. I've seen some dyno results for other intakes where the divider was removed and as a result, hp and torque improved. This thing is really going to choke my 470 to begin with so; again, I think the extra volume would be more important.

I'm no pro so; I'd like to ask the more knowledgable individuals on this site what you would do?
