If you are running the hot side on the drivers side the compressor will hit the trans bell housing, I wanted to run mine that way so I used a log manifold kit and used the exhaust flange as a spacer with longer exhaust studs. I am running a cast manifold and compared a couple, they all had the same spacing as in how far they are mounted from the block. I have another manifold kit with the flange pm me if you want to do it that way.
