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

Might as well. It’s only money.

Inspect your stuff and see how it looks. I don't think Id spend the money on a stroker kit, personally. Not for a tahoe but then again, who knows.

Contact the machine shop that did the work and explain to them its eating thrust bearings. They should offer (I would hope) to do a better job, if you think thats the problem. If everything else is checking out and the thrust is the only bearing ******* up, seems like thats a good starting point.

Yeah, that's the plan.

I really want to try rolling in a new main at least once more before the engine comes out anyways...
I would cry if my new crank died due to an existing issue with the transmission...

if the crank is totally trashed, then it's plan B

kinda what I'm thinking.
I'm taking this as a learning experience.
Best way to learn is repetition.

I always wanted to do an engine build anyways.
After the second go-around I'll nearly know what I'm doing!

And my vette came with forged pistons, not that i can hear anything over its exhaust anyways.
But I always like to let my crap warm up before driving anyways.


Pluses,
Forged pistons would handle tuning mistakes better
stroker crank will give me more down low power and torque.

Last time i had the pan off, i noticed that the crank walked enough to offset the piston to rod alignment.
Probably not good...

Bads
more money.
I really need the hoe back soon; it's getting annoying having to share a car with my wife.
I have to find a machine shop to do the balance job.
(But I'll probably just use the same one again... not like they are doing the crank polish)
Kit is not in stock (not much in stock), so I'll be waiting and hoping they actually come in stock for the projected timeframe.

I used the lifter kit they have and back ordered them. Got em a week later. Plus the kits are more like “kits” that’s why they require balancing. Everything is Al a carte. Something on the kit is out of stock that’s why the kits out of stock. Back order that shit and you’ll get whatever they have first then ship out whatever comes in. Also my lifters had a thanksgiving ship date. Came well before that.

Need opinions on which setup to go with. I’ve got the C-shaped led acting as the drl (also comes on with park lamps). Should I keep the lower bulbs as park and turn or make it like the K2XX Chevy suvs and have them only as turn signals. The side marker light would remain on the park lamp circuit.

I vote park and turn and if you are really nifty with the tools make the side marker alternate with them.

I second that notion…

Ordered a set of amber Sealight LEDs for the fogs. Swapped back to the stock bulbs this morning to see how they compared to the Allah LEDs I had. Well, it might help if I aimed the lights up a bit. they shine on the road so close to the truck you cant see the spot over the hood.

Why do we overlook the simple things???

Has anyone replaced their “plastic” Oil Galley Barbell with a machined one?

Used the improved racing one. Not that cheap Amazon one. It has two o rings.

I used this in two builds. One is running. I also used the oil pan baffle and windage tray. Very nice stuff.

Very good stuff, i like how it has an o-ring for the unfiltered side.
It also has a threaded end to assist with removal.

It was a tight fit, but i prefer that.

it's also beveled and thinner than the original to assist with oil flow.
the original would protrude slightly into the oil pathway, looks like lots of thought was put into it.

They also make an oil pickup tube support.
I'm also running that...

Great, now you guys have me adding parts to a list of things to buy that I didn't know I needed.
