V-8-POWERED H3 ALPHA

50:1 with a V8 would be pretty powerful.
The crawl ratio appears to be lower due to the 4.10:1 axle gears.
The auto tranny 1st gear is 3.06.


Meybe they will put in stronger tie rods too?

The 5-speed stick and front axle would have to be up-graded to handle a V8. The t-case should be fine.

Automatic only behind the V8.

Yeah that was a stump puller for sure. That 4 speed, and transfer case combo was bulletproof. I will buy another one someday. I love them.

1968 F250 w/390 and granny tranny (4-speed w/granny gear). 4.10 gears and it would pull your scout pulling your house Miss that truck

agreed!!

It appears to have the same 5.3 engine that is in my 07 Tahoe which means it could be made a flex fuel vehicle, and being the little power house with a V8 it will be a big hit commanding a premium price of no less than 50k.

XM DUDE, people in the know already said that it's only $2k more. I wasn't guessing when I said that, so put your mind at ease about the pricing. Remember, the H3 is a pricepoint vehicle. People that would spend $50k will more than likely upgrade to an H2!

I could give a rat's patootie about flex fuel capability. There's not an ethanol station within a thousand miles of my house. It's a gimmick unless you live in freakin' Iowa. The one good thing good about flex fuel capability is that the fuel delivery system can take the funky chemicals without drying out and cracking better. When they went with benzene and MTBE in our fuel here, I had premium Gates hoses and gaskets turning to krap in only a year.

Depends on the Scout. I put the wide ratio (granny tranny) in my Scout, 4.10 gears, and the 3:1 conversion. It had lockers front and back. Four tires against maybe two in the ford (if it had a rear limited slip) I dunno, I'm thinkin' it wouldn't be pretty for the old F-250!

About the 4.10 gears with the auto. That's the old debate of what's better, a stick or auto. That torque converter makes that 50:1 a lot more feasible. Still, I sure would like to see the new six speed in the H3!!! The gears are stronger in a 4.10 diff too (not much as say if they other was a 4.88, but still, it is stronger)

Hmm, so from what I have been told by factory trainers and engineers from anther line. The engineering spec for a torque converter is 1.8:1, that is both slip, and torque multiplication.

For your basic crawl ratio spec, 100:1 is the target range for technical 4-wheeling, like rocks and really rough terrain. So given the specs on the H3 the crawl ration is more like 90:1

1.8 x 3.06 x 4.03 x 4.10 = 91.0:1

The big problem with the 4:1 t-case is that it really takes away from the capability of the rig in some situation, but enhances it for others. Mud and deep sand really need higher wheel speed so the 4:1 t-case probably wouldn't be a good choice for that. But on techincal trails and in the rocks, the lower t-case gearing really shines through. So pick you poison when selecting your t-case gearing.

Do you choose men with the same technical savey that you presented the above with?

I like these kind of posts

Yeah thats what I was thinking. I had the granny first in mine too into 5.13s in the axles I dont know...they just dont make em like they used too, the old fords, old powerwagons...all awesome rigs!

Pretty stoked on the H3 though. I cant complain. Plenty capable.

Ive had some old rigs that I miss, but when I think back on the lack of a decent HVAC system, poor brakes and steering, fuel system troubles, gear whine, oil leaks etc. I do a reality check and turn on my heated seat in the H3 put on a Dead cd and hit the road.

If you get sentimental put a picture of the old beast on your visor.

I'd like an old work truck again but not for daily driving but maybe on a ranch or kept at a cabin etc.

Same here.

The V-8 upgrade should be OK mated with the 4 sp auto. But if they made the 6 sp the automatic for all models, it would help with the 3.7 lack of power, and make the V-8 a monster.

[Huck BB62]

And not to mention, help mileage.

I really like the looks of the H3 and would like to have one, but what's up with the 1985's technology 4 speed auto?

GM should, at least, have a durable and reliable 5 speed already in the H3.

If you haven't experienced it, you can't imagine the control from a triptonic style 6 speed, that also allows you to shift manually, gives you, especially in low range.....!!!! H2 owners will soon find out.

I'm not sure if simply the addition of a V-8 to the H3 is enough to get me to jump for one.
