6.0 V8 H3

[BuzzH3]

I know that this has been posted before and it may even be the same H3, but this guy was at an Off-Road event I went to last weekend. It was a green H3 with a 6.0 liter V8 in it. He said it was the engine and transmission from an H2. He claimed it was putting out about 425HP!!! He has 35's on it and a 2" body lift. I have to say that it was very well done. It almost looked like it came from the factory that way. From the inside, it looked bone stock. Everything worked including traction control. He didn't change out any other driveline components.
He was running all of the trails that we were running. He also gave me a ride in it on the road. He did several full throttle launches and everything (at least for now) seemed to be holding up really well. It was very impressive. He claimed that he was getting about 16-17MPG!!!

I took some pictures that I will post when I get home tonight.

v8 from gm is comming for the Alpha H3 but don't think it will be a 6.0

Well, If it is real and only the engine was changed I sure hope the TOTAL drive train can take the torque that the power plant puts out...

If they put a V8 in the Alpha I hope they offer a 5-speed and Adventure Package. When can I place my order

They would have to upgrade the manual trans to handle the tourque of the V8.

Maybe drop in a new Vette engine???

It is the engine AND transmission from the H2. So far it seems to be a testament to how well built and heavy duty the H3 is from the factory. He also mentioned that he might put a supercharger on it too! I would imagine that would put the HP over 500. I'd be interested to see if things start breaking then!!

Sounds like a nice package!!

Alpha does not get a 6.0L. If they put the H2 drivetrain in the H3, there will be little aluminum pieces from the front axle laying on the side of the road. There is NO way that front axle will take that torque. In fact, the front axle on the Alpha when it comes out next year will be different than what is on the current H3.

I wonder about that "specially constructed title".

[BigBill]

Hummer H3 Alpha...is that what the model next year will be called, with the v8?

[Urban Ops]

I heard the H3 Alpha was still going to be the I5 with either a turbo or a super charger. With the reason GM went with the I5 in the first place, light weight compared to a V8, short block compared to a I6, I doubt we will ever see a V-8.

It's called "SALVAGE"

Sounds like it was totalled and he rebuilt with a V8, although I question wether it is really the 6 liter. Is there really enough room in there for that motor?

It is. I saw it first hand and rode in it.

I am far from being an expert on diffs, but if the front diff was that weak, wouldn't they be popping all the time when you put it in 4 LO and climb over rocks and everything else. With that gearing there has to be an awful lot of torque at the diffs even with the I-5. Now, granted if you had the 6.0 and drove it like an idiot and hit full throttle every time, I could definitely see parts breaking. If you drove with a half an ounce of sense though, it seems like it should hold up pretty good. Having said all that, I still would never do the conversion in mine. I'm just waiting for the Alpha!!!

Remember the Rotory Engine OPTION thats coming...
