V8 H3 Alpha

[H3.007]

I just looked at the specs for a 2007 Yukon. Isn't that a heavier vehicle than the H3? If so, it is getting comparable gas mileage with a V8 and obviously more horses....

And would such a comparison be stupid?

If only the real world gas mileage of the Yukon was even close to the EPA mpg numbers. Everything I've seen so far indicates mileage around 12mpg.

What's wrong with the H3 drivetrain behind a V8? The rear axle is just a narrowed version of the 1/2ton pickup 10 bolt. The 4L60E trans. is what goes in the same trucks behind many 5.3L and 5.L7 V8s from the factory. The transfer case I admitedly don't know much about, but it looks VERY similar to the auto-trac transfercase which is also found in many fullsize 4WD GM trucks. That leaves the front axle as (IMO) the only part that isn't up to V8 power standards. Now, GM used to make a cast iron version of the mid-size IFS axle (I think it was the ZR2 S10), so I would venture to guess the H3 Alpha would have this as well.

In short, an H3 Alpha only needs a 5.3L V8 and a cast iron, locking, front diff in addition to the currrent H3 Adventure components to be a reality. If they want to throw in a body lift to clear the engine some more and maybe fit 35s, all the better

I agree a 1 inch body lift with 35s would be my ideal H3. I love the articulation and that wouldn't change it abit. I would also say the alpha should come with the HPN shocks. All that and above, Good lord that would be one incredible stock vehicle.

I'd be more than happy to let them use mine as a real world test vehicle

I am completely happy now with what I have. Unfortunately I am a chop aholic. If I keep the H3 for a long term rig which could very well will be the case, I definatley with play with the engine swap idea and 4 linked Dana 60s or ford 9"s front and rear. Not till after the car is done for, and starts to fall apart on its own, and considering the way we take care of our vehicles, wont be for a long time. I love my H3!
