this is why i love owning and fbody, the V6 cars all came with 2 piece drive shafts, but the V8 cars had 1 piece. I picked one up for 20 bucks lol. As for the 1 piece showing more power, it doesnt show more power as much as it does torque. When i switched over to a 1 piece, it showed a gain of roughly 10 ftlb.
