RJ: Definitely go with the 12-bolt, and with a "pro" 9310 steel gear. You will definitely break the teeth off of the gears with that much power and weight if you use a "street" 8620 steel gear. I have an Olds that I've run for quite some time, weighs around 3800 lbs. and has run a best of 10.85. Add to the fact that nobody offers a "pro" type gear for the GM 10-bolt that I am aware of.
