Ok guys, i'm back with a few new questions. As an update, I went with the mechanical clutch setup, and i am going to for-go headers, and use the wz (someone correct me on that if i'm wrong) manifolds. now, i have some new questions though. first of all, i know that there is a g-body specific bellhousing (the ballstud being in a certain location), but it's only a chevy bolt pattern. seeing as i'm goin with the olds motor, i need to kno where exactly the ballstud is supposed to be, so that i can move is in my bellhousing. also, I did get the actual floor panel for the shifter, so I was wondering about the shifter install kit. and finally, will i need to change my driveshaft? My current setup is the buick v6, with the 250c and a 7.5 rear. my new setup will be an olds 350, borg-warner super t10, and a 8.5 rear. will i have to change my driveshaft? if so, where can i get the right one? If i can get some help with all of this, i'd really appreciate it!
