h2 feeling a bit sluggish when towing, what are my options to increase torque?

[HummerMann]

I've looked at supercharging mine several times. Mark can tell you a lot of the costs and performance differences in supercharging vs diesel. I've also read on the brand X board that the Z06 LS7 505 hp engine is a straight forward bolt in on the H2 except for the electrical harness and need for a custom oil pan. The dealers are quoting 15k for the LS7 crate engine, but I've seen them on EBay for 12k. My next concern would be if the transmission could handle that extra hp and torque. For less than half that though you can put on a supercharger.
