Next get those gear's installed & contact Andre @ <a href="http://www.edgeracingconverters.com" target="_blank" rel="nofollow">www.edgeracingconverters.com</a> and He will set You up with a converter <img border="0" alt="[burnout]" title="" src="graemlins/burnout.gif" /> .

If You can't afford to do everything at once then do the gear's, tranny mod's, and converter now & save for the cam down the road. You can't believe the difference you will feel when You put the edge converter in Your ride <img border="0" title="" alt="[Eek!]" src="eek.gif" /> .
