I need some help. I have a 91 RS that I swapped in an '87 350 tpi with a new cam. I plan on getting some 2.02 heads in a few months. Ok, here's my question, do I just switch out my gears or do I find a new rearend altogether from a Z or IROC. Also, what gears should i get, 3.42 or 3.73. Thanks guys.

 

either will work, lot will depend on your ability to swap gears, or just the rear. ratio depends on what you want it to do, or what you want to do with it. little more info would help.

 

well if you have drums brakes, no posi, and not a good ratio i would think into getting another rear with disk brakes at least and work from their. do you want a 9 bolt bw or a 10 bolt rear end..
