Default I5 or V8?

I'm still looking at buying an H3? My question is about the engine. Is there a any differnce between the 3.5 and the 3.7, as far as the driver can tell? And is there a huge difference between the I5 and the V8? They're advertising a 60HP difference between the V8 and 3.7L, is it work the extra $8g?

theres other difference besides the V-8 too, such as the cast iron diff etc.. but the only way to really know is to go drive them, keep in mind the v-8 is vquicker but it also becomes a heavier car.

I plan on going with a lift and 37"s right off the rip. I'm worried about the I5 being super slow or having to down shift all the time, when im on the highway. And when I'm wheeling and hit a mud hole, I want to be able to romp down on the gas and spit mud all over. Plus with the V8, its a gm V8 that you can get more parts for. I just want to know what you all think. I'm not wanting to shell out the extra cash if the I5 can keep pace with the V8.

Well, it really depends on how you will drive the truck.

The difference between the 3.5 and 3.7 isn;t all that noticable.

The weight of the vehicle between the I5 and V8 Equipped trucks are very minimal. The I5 is 4700lbs and the ALpha (V8) is 4851. If you plan to wheel and run 35's, make sure to go with the off road susp. package. That will get you front and rear lockers as well.

If you plan to trailer anything the V8 is the way to go as well. You're at 6,000lbs vs 4500 with the I5.

I have owned tow H3's, one with the I5 and one with the V8. I got rid of the I5 due to the lack of power.

Go on HUMMER.com and order yourself a brochure. Than go drive the trucks. I guarentee if you drive the Alpha, you won;t even consider the I5 if you are n;t going to tow anything or have more than one passenger.

You cant get the 3.5 post 06. And not worth 8K unless you are pulling over 5k pounds

I see someone mentioned the different towing wts, 4500 vs 6000.
I thought the limiting factor with the I5 for minimul towing was the transmission. Do the I5 and V8 have the same transmission?
