I like your idea. I'm going to try to do something similar myself. I don't know much about welding though. On the other hand I have a college machine shop at my disposal so I've got a bit flexibility there. I've told myself though that the intake would be the second project. I want to rig up a fuel injection system for my 250 first. But either way I'm all talk right now. So we'll see. I can't offer much help but good luck!
