For the power, a blower of some sort would be just the ticket. Forced induction is an easy way to make power. Trouble is, it certainly isn't cheap..... and given the age of our trucks, most manufacturers don't support them any more. A custom turbo system, or, finding something on the used market might be your only choices.
For the trans, check out the Mega Viper. It'll take that kind of power without any complaints at all.
