gear ratios and torque

here is my thoughts. a 2.76 gear would sure kill that big cubic eng torqe aka help to keep it from spinning. But if it spins it will spin for every!
If you have 4:56 gears, there is a chance of lifting a little and getting it to hook.

Now that don't really answer your question and neither does asking a question.
Were is the torque curve going to be on this eng. idle to 5000? (2.76 gear) 5500 to 7500? (4.56 gear) and a big wheel well tubed rear end. (tire height will very this some)
