I see you have a detroit rear as per your signiture, what rear end are you using w/ your 700r4 and what ring and pinion? I am planning the same drivetrain swap. But it will be built and assmbled on my spare frame, so I can continue to drive my Raider. Then I will just drop my body onto the new frame. It just will be a giant bonus when I get the better gas milage w/ the boost in torque and HP. <img src="/forums/images/graemlins/kewl.gif" alt="" />
