Thanks

With this heavy a car, 12 bolt, no question.

I'm preparing to build a 34-3500 pound crate motor car and we're going to utilise a 10 bolt. I still have my concerns but after a few consultations. I am less afraid of these rear ends on a lower HP footbrake stock class car.

If I were building a high torque engine, that would be launched by either a stick or a trans brake, if I were limited to or desired a GM rear, a 12 bolt would be the only choice.
