I have a 99 chevy suburban that i am looking the make a few more horses out of. It has a Vortec 5700 L31, basically a gen I small block 350 v8. Everything is stock and i am guessing that the performance is in the 250hp/300lbs range. I know that you can pull at ton of power out of a small block, but I'm not sure exactly what the best way to do it. I would like to see it maybe up in the 300hp range if possible with out going crazy on this motor. We use the suburban as our primary car to go up and down i-70 for skiing. On flatlands, the power is fine, but pulling 6-7% grades with people and gear at 70mph is a work out.

Can you guys give me some advice or point me in the right direction?
