You'll have a much stronger rear end and many companies make rear disc brake conversions for the 9" Ford.
Dave, reread post #8. My 400 was stock except for a Isky 30-30 cam, Offy 360º intake, 650DP and headers I put in a 3100# pressure plate with an all synchro 3 speed and I could eat spider gears any time I wanted and he has basically the same rear end.
