The Track-lock can handle only 400HP?? If that's the case, why would the factory put it behind a 71 Hemi at 425HP?


Probably money and I believe he was talking about racing it and using it hard not just regular street driving. Somebody took the good guts out of that rear and replaced it with the weaker parts.
