Word on the street is that Full-Race is testing a stock location Full-Race manifold for at least RWD SR's. What I was looking to find out is what is the benefit of running a top mount aftermarket manifold vs a aftermarket bottom mount, in this case a high quailty unit such as the Full-Race manifold.

Also, I believe you cannot run a/c with a top mount Full-Race unit with stock lines? I read this somewhere on FA along time ago but wasnt sure.
