What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Doubeleive]

Front is a matte, phosphate like, finish. Rear is flat black. @Rocket Man the ends of the rear are pinched closed if i look hard. I've never heard of spring steel in a tube before.

got a picture? not sure what color phosphate is googling shows everything from light blue to purple to green.

 

[Doubeleive]

Serviced the front diff, I don't recall having it done in the last 50k, the old fluid looked like new, clean as a whistle, not even a sliver of metal on the magnet either,

Good deal.

The guy here who owns the one E85 pump within reasonable driving distance keep his price right at where Costco is offering 87 regular. It never makes sense to fill up at the E85 pump when 87 is at the same price (right now, about $3.05/gal).

Unless you have a 6.2l that requires higher octane than regular 87 unleaded

It still doesn’t work as the up charge for 91 at the volume dealers still doesn’t you to a cost per mile equal to E85. There just isn’t enough volume/competition to get a price delta large enough to make it worthwhile.

The final nail in the coffin is one pump in one place, owned by a used car dealer who specializes in novelties.

I have a giant Lead shoe I wear while driving, but with the border patrol style front bumper cut, tow mirrors, 33" tires, and front end lifted 3"s(rear only 1"), I average about 8.5mpg on corn and 10.5ish(I haven't run it in a long time to do any numbers comparisons) on 87.
All highway is maybe only one or one and a half MPG higher for each.

Our Sierra with the 6.5" lift and 35s gets 9 MPG on E85 (72%) with about half each of highway and city driving. She gets 15 mpg on 93 at 75 mph. This is with the 6.2 motor.

I just bought a complete 6.0/4L80e..... should be here in about a week or so

...My education on the topic of torsional rigidity was that most of the strength is in the outside of a tubular rod or shaft. And the stiffness will have as much to do with the metallurgy as with the physical dimensions.
...

Just in case anyone is interested, the torsional stiffness varies by the fourth power of the diameter. Put another way, if you keep everything else the same (bar length, material, etc.), and just vary the diameter of the bar, doubling the torsional stiffness of the bar requires only a 19% increase in the diameter.

Because the outside diameter has such a large influence on stiffness, a hollow bar doesn't lose as much stiffness as you'd think, because the material toward the center doesn't contribute very much. Using the example above, if a 1.19" bar is twice as stiff as a 1" bar, a hollow bar with 1.19"OD and 1"ID is just as stiff as a solid 1"OD bar, but only weighs 42% as much (if I did the math right).

Can anyone recommend a brand of split loom they know to be durable for under hood use? The OEM wire harness loom around the engine is in terrible shape from becoming brittle and a lot of it is completely gone.

On previous projects I’ve used whatever was handy but given the poor performance of what GM used it’s got me thinking about the (lack of) durability of Chinese plastics.

I don’t mind the price for quality stuff. Rather do it once and do it right.

Thanks in advance for any recommendations.

I sat in my hoe and made sounds that loosely resemble engine noises.

I was told there'd be no math.

Actually I went to Harbor Freight and got a bunch of their stuff and got some black wrap tape from amazon, not electrical tape.. its a sticky shrink wrap. Been going strong for about 4-5 years. HF only has up to 1/2" but that was good enough for everything except the main harnesses which had not crumbled away

I used Summit braided wire loom, to redo the entire engine compartment, when I yanked out the engine an dtrannt last year. Its cheap and comes in decent lengths and in both black and Chevy orange (UGLY)!

I suggest getting the easy wire loom tool, make sit easy to slide right on. I also used 4" zip ties to hold the long lengths together

I also live in Florida so all of mine was cracked and busted, so I didnt want to deal with the plastic crap anymore

Yeah, this truck was in TX and has over 10k hours engine run time. I think it spent a lot of days idling in the desert with the AC on and the under hood temperatures roasting.

Well I didn't ask you to do any. I'm still in recovery from being an engineer. So cut me some slack.

.375 = 3/8"
.375 x 2 = .75 or 3/4"

Some math to make people loose their minds...
