So what is the easiest route for 3.4 ( non crusher ) install , cut the hood for the 4" upper ( would rather not ) and use the stock lower / cage , get the k-member spacers for above set up ( are tranny mount spacers required as well , pinion angle change ? ) , would like to go with the smaller (underdrive) lower Metco ring and the upper 3.5 pulley but others say they have had crank snouts break ( don't want that and would like to hear from people that this has actually happened to ) . Any real life experience from those of you with the 3.4 appreciated .
