Im looking at replacing my '01 Subaru Impreza 2.5RS because the tranny wont hold up to the amount of power I wanted to build the engine up to. I've decided to buy a truck and have narrowed it down to either '02 GMC Sierra std. Cab or Dodge dakota Club Cab. both would be 2wd. What I need too know is what is the strongest engine/tranny combination for each of these trucks and how much hp/torque would I be able too get out of them before I'd have to start building up the engine or transmission. Im a bit of a power freak so I want to make sure I get the vehicle with the most potential. Thanks for any advice.
