Exhaust Chimney to Cooking Grate Distance?

    I am starting to plan a build (maybe two), and have noticed looking at some of the builds that there are variances in the cook chamber as far as distance from the bottom of the chimney to the cooking grate surface.  I was wondering if there is something to this as far as building heat or smoke in the chamber.  What are the pros and cons of closer or farther away from the grate?  

    I am sorry if this question has been asked but I tried a search for it and could find the answers I was looking for.

    Rowdey, I think the biggest thing is that the stack being lower to the grate keeps the smoke from just flowing up and out to fast. Letting all the heat fly away. On my reverse the stack is about 1/[​IMG] below the cook grate. I like being a little different so I cut wedges and rewelded my stack to make it look like it was bent and ran it out the end of the cook chamber.
