What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Rocket Man]

Thank you. I have a hd hood off a 02 chevy I plan on having cut and fitted for Denali. I like the buff looking hood.

HD hood? Oh, I forgot to congratulate you on finding one with such low mileage. Mine had 120k on it when I bought it a few years back, and that was hard to find. Nowadays with less that 100k on one is rare as I’m sure you know. If you ever want ideas, my build thread is linked in my sig at the bottom. If you’re using a phone you’ll have to rotate it to see it. There’s about 340 pages (and growing) of reading lol.

Yes a 00-02 2500 hd hood off Chevrolet. I think they look good because the front is raised and not so sloped like the Denali hood. And thanks I seen it pop up on Facebook locally for sale and I just jumped on it. I knew I wouldn’t find another one like it lol. And you have nice lookin pewter Denali too! I wouldn’t mine having that 6.0 tuned a little bit.

 

[Scottydoggs]

Glad I asked. Mine are original and I have 223k on the truck now. I haven't noticed any idle or performance issues, but I suppose they are due for a change.

new 02's might net you a few mpg. they help control your fueling.

Yes, get it tuned. You won’t believe the difference. The trans gets tuned too, so shifting is way better ( faster, firmer) which makes a huge difference too. If you don’t have somebody you use, Black Bear Performance is highly recommended here.

I have a guy that has the GM programming so I guess I get him to tune it for me and the trans too! I work on GM 6.0 everyday(I’m a mechanic on a fleet of abut 90 GM trucks) but I do not program anything lol.

Lloyd makes some nice stuff, not cheap though are they.

No. Definitely not cheap, but high quality. I debated a while before spending that much, but I hate floor mats that move and don’t fit right. Hopefully last set I’ll ever need for it. Came with grommets and anchors, but I used the Klaw ones I saw you posted about. Thank you. Those are nice.

Yeah that’s a nice combination you got there. Both quality products. I love those Klaw anchors.

I wouldn't even want to get in with my shoes on! I wouldn't want to dirty those mats.

On another note---
Well, I tried getting that O2 sensor off. I used heat--I let it run for awhile--penetrating oil--FORCE! No luck. Once I started to round the nut off I stopped.

New valve cover gaskets and grommets. Put on coil packs, plugs and wires. Put dipstick back in. Noticed intake gasket had a few leaks, will put on tomorrow with new gaskets. Noticed some oil coming out of intake, needs a cleaning bad. That’s half of it s cleaning the parts before putting back.

I'm just super paranoid of messing that bung up, or the threads or tearing the metal on the header.

i know exactly what your saying. china headers are thinner.

need to give it shot tho, once it breaks free its coming out easy.
