I would. Tomorrow. Be damn happy to.

comparing a full size GMC to the H3 is stupid

Maybe, but big torque is good.

I love my truck, I don't complain about it, I'm not bitchin.

But if they come out with a V8, I'm getting one.

the need of power is in the foot of the beholder. There really isnt a point to a big engine if you dont really need it. I personally need just a tiny bit more power for towing, but i still got the H3 cauze it outshines most of the more powerfull trucks in almost every other aspect. Im still loving it, but if something more comes out in the h3, i might think about upgrading.

WHAT? It's all a matter of power vs. weight.

Geez, I sure hope some of you guys never make it on a study panel.

Para, that's just what confounds me.

The H2: 325 HP (@5,600 rmp)/6,400 lbs = 1 HP/19.69 lbs

The H3: 242 HP (@5,200 rmp)/4,700 lbs = 1 HP/19.42 lbs

Thus, if these numbers are correct, the H3 is about 1.4% more powerful than the H2 per weight carried. If you add the same equal weight, say 500 lbs, of people and cargo, to each vehicle, this does favor the H2, a little, but the ratio then becomes 1/21.23 for the H2 vs. 1/21.49 for the H3, which is only a 2.1% advantage in power/weight for the H2.

Is the reason the H3 is/seems less powerful because of the higher rpms required of the I5 or something else?

You said a mouthful but you left out the most important factor - Torque. While HP is how quickly you can get "work" done, Torque states how much you can do.

I understand, but I thought that the H3 can get the work done, it just takes it more time (i.e. slower acceleration) than some desire.

It's because of the difference in torque curves.

The H3 peak torque is at around 4000rpm I believe. My old truck has just 210hp, but is much stronger than the 3.7L H3 off the line because its peak 300ft lbs come in at 1800rpm. Both trucks weigh comparably the same and have 33" tires, but the old chevy 5.7L has much more grunt, at every rpm, even though it only has 3.42 gearing!

Don't get me wrong, I think the H3 power is plenty adequete as it is. It can still get you in some trouble with the law enforcement officers if you want, but you just have to keep the revs over 3000rpm to get them to notice you. That's just the nature of a small inline engine. The I5 makes a great base engine, but an optional V8 with more low-end grunt would go over very well with just about everyone.
