I've used the power-trax unit in a '96 Dodge Dakota with a warmed over 318, and my '67 LeMans with 350 and 400. The dodge had about 275 HP, and worked great. The 8.2" R/E in my '67 worked well with powertrax and the P-350. But when I stepped up to the hot 400, I had problems. The axle shafts twisted and the carrier deformed a bit. I think the power trax units are good for about 400-450 HP. More than that and the factory carrier and axles start to go. The only thing that kinda annoyed me was the clicking and popping around sharp turns. Otherwise it worked fine, until the factory parts gave up.
