vaccum

Was wondering if there was going to be different vaccum rules between the big blocks and small blocks this year. It seems to be pretty hard for a small block to be competitve against the big blocks with the vaccum being the same for both, in my experience with pulling vaccum the big blocks seem to be able to pull it alot easier with the displacement compared to a small block.
