the supersoupe swap will be a damn fine idea. 3.45 gears and a detroit truetrac and it should run high 13's on a stock setup.
they are very good bases to work with. ported heads and open up the ports on the supercoupe intake, weld the silencer ports on the blower for more of that roots whine, cam it and make sure you don't use the GT mufflers on he GT catback. cut them off and get some Thrush 2 chamber (flow 40 knockoffs) for $30/muffler from jegs and it will run and sound damn good.
used 3.45 gears can be found on EBAY for about $50. it's a great gear for the torquey M90 and the speedo will be dead on with the 23 tooth speedo needed to calibrate it. 3.73's wouldn't be bad either.
great place for M90 go fast stuff
