I'm curious, I have found a ton of 5.4l superchargers forsale and am curious if they would be interchangable with a 4.6l. I know this is a noob question, but I am just curious if manifold parts are the same. Let me clarify, I'm talking about the eaton roots blowers and manifolds. I know the centri head units are the same. And I also know that there is a 2v and 3v 5.4l, I'm just concerned with the 2v. Also, is there an adapter that will allow a 3v to set on a 2v, I know you can go the other way, from 2v to 3v, but does anyone make a 3v, to 2v?
