I thought about this and i am still seriously considering it. Only problems are price and finding a one in good condition with a transmission.

The limiting power factor is the transmission and brakes. As far as i can tell the stock 4l60e is safe up to 360 foot pounds so if i do major power upgrades, i think i will need to build the transmission accordingly. This suburban is chronically under braked, even with the best pads and rotors, it takes way to long to stop. Small dics up front and drums in the back don't cut it on a 6000+ pound suv. All the power in the world means nothing if you can't put it to the ground and stop it. Bigger brakes mean new wheels to fit the bigger rotors and calipers.
After much thought i realize this is going to be an expensive endeavor. I estimate about 5k to do it right (engine, transmission, and brakes) and i don't know if it is justifiable for the 20 or so trips a year that we would like the performance. The burb has 150k hard miles and so far has been an absolute champion workhorse. For the last 10 years it has been ridiculously reliable and it will never leave the family, but i am hesitant about a 5k investment as is is not broke, so don't fix it kinda thing.
I appreciate all the discussion on this topic.
