I have a chance to buy a 8 bolt max wedge crank for a great price but for a few dollars more I can get a lightweight crank from 440 source and im sure its 6 bolt I plan to do a little strip time which would be better also can I get away with using a 23 spline tranny vice 18 spline expensive trannies or could I buy a 23 spline and change over with parts from Brewers thanks
