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

[George B]

it should hold until something wears out now, that was the most logical solution to me

That would be my go to fix. Actually should be done as PM.

Yeah I really need to get my fat ass under mine and check it out with the mileage I got. Keep forgetting about it.

Nearly 3k for those heads, and they ship them in the AFR box showing on the outside.

Anyone have the weight of these GMC 20" wheels ? I know it's the only picture of the Tahoe.
Looking for lighter wheels.

no idea but the aluminum ones are the lightest, like night & day compared to the chrome ones.

I took mine to get an emission test and..... It PASSED!! This is even with ARH lobgtubes and their cats. I'm also cammed and slightly bored out to almost 6.3L.... Shout out to Blackbear for the awesome tuning of this beast.

With blackbear, do you have to buy their tuner?
or is it a lease type of a thing?

I would love to just use hptuners and my licenses.

Anyone have experience with Comp cams full roller rockers?
I'm looking at the ultra pro magnum rocker arms.

secondary would be the comp cams ultra gold aluminum rockers for $150 more.
looking at 1.8 or 1.82 ratio...

Yella Terra FTW.

The bushingfix.com rubber bushing apparently does not like the California heat wave, I was waiting in line at the pharmacy and when I went to pull up my shifter decided to go limp dick, had to crawl under and push it back on, managed to get home and it popped off again so I macgyvered it by drilling a hole in the nipple, washer and a cotter pin leaving the rubber bushing in place, should be good for a long time.View attachment 305400

WTF? I don’t understand why an “improved” part would fail faster then the original. I still haven’t had an OEM one break.

Weird!
On a probably unrelated note.
I had issues with poly suspension bushings on my vette.
all was good until i was out in the heat for 30min or more (100+).
they turned to mush and my suspension had a ton of play.
It really fkd with me until i had a good alignment shop show me what was happening.
