J,
That six gun ain't gonna help you. I had clutch wear with an Edge EZ set at 70hp. You might want to upgrade the transmission. You might be surprised at what is floating around in your transmission pan, I know I was before the ATS stuff went in. These 48RE's will handle a stock motor reliably if taken care of, but you start throwing HP and torque #'s at it from some of these boxes, things are going to break. Just my . 02, been there, done that.
