OK I have heard everyone talking about the ford powerstoke ic and using them on our cars. I have aquired a doge cummings fm from a school bus and was wondering if anyone has tried one of these or am I going to be the guinea pig? This thing his huge and has 3" inlets and outlets. From what I can tellby looking I will have to take more than half off of it and weld the tanks back up. Anyone attempted this?
