The easiest way would be to order the BDE adapter bell housing and run a GM th-350 or a TH-400 tranny. The 400 is an all mechanical tranny so it doesn't need any wires. (Im not sure about the 350) The 400 can be built to hold well over 2000hp so it has no problems with anything our z's can throw at it. From what i understand is that Greg Dupree (Specialty Z) has this tranny in his car. Just a suggestion/option. Good luck!
