I kind of want the new transmission first because the one i have is complete junk. Well after new clutch, flywheel, and steeda 3 piece clutch cable kit it still blows. I think its time for a brand new one. The rear end i might just try to find a cobra rear at a junk yard maybe. But then im going to have to buy new rims and tires to fit the bigger break rotors.
Afterwards im looking to build a 4.3L long rod stroked out monster stage 3 everything. and then buying an 11# pulley.
its only a difference of .05:1 ... imo if you think that you will need that extra 5 hundredth of a gear then go ahead and spend the 2.5k that a t56 conversion costs... you are getting a great tranny for that price but imo you can get a rebuilt tranny that has been re-geared for say something like .59 over drive or .63 over drive... but if you want track only re gearing it to .79 is also possible
