A diesel conversion would be great BUT I don't want to spend 30K. Like I said Im not looking or race car just some grunt to pull my trailer twice a week. I only get about 10 mpg right now so I doubt an 8.1 swap or a built 6.0 is going to change the mpg that much.

I could go buy a diesel truck but I like my H2 and can buy a lot of fuel for what even a high mileage diesel would cost. Not to mention I still have to pay for fuel, insurance, and maintenance on the diesel.

I know some people think the H2 is a terrible vehicle. I have owned Jeeps, diesel trucks, 2 ford raptors, and custom built rock crawlers. None of which could do everything as good as my H2. They all have their place but IMO if you want one vehicle that can take you in the woods, through the snow, over the rocks, tow a trailer to work, and still be comfortable enough with 37" tires to take the wife out for a night on the town you have to have an H2!!!

Just my take on it.

Heres my take on it.
I have a Vette and my H2 and from what I understand the engine are extremely similar.
So the questions is if you are just looking for grunt, why not change your gears?
I have a plan to change my gears out to something taller for both the Vette and the H2. Gives it the ability to not run the engine as hard while still pushing it up a hill.

I notice on my 03 H2 any kind of an incline will cause my truck to gun the gas when I am using the cruise. (and i mean any kind... like going over a bridge on the interstate)

So maybe, if you have the funds you can beef up the engine, work the tranny and gears some and that should make you happy.
And if you need more power, I would think a 112 or 122 maggie could help you out and could probably be obtained pretty cheap.

Probably come in alot less then a 8.1, allison, and all the labor and hassle to figure it out

Ever think about stroking the 364 to a 408? EuroHummer had/has a CRAZY fast deuce...he posted some interesting links to Vortec performance stuff in this thread. I know you're not going for speed...but perhaps some of the info will be helpful.

I saw an H2 at the old Lynch Hummer dealership where they had dropped in a Corvette Z06 505 hp LS7 crate motor in a 2006 H2 and they said it was almost a direct bolt in except for a custom oil pan with the electrical harness being the most difficult part. That H2 is still in the owners hands somewhere in St Louis I believe.

Well the plus about the stroker, which might be something he is trying to go for, the torque
