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

[Walchit]

Well, what ARE you doing? Full rebuild? New bearings, rings and hone?

I was trying to avoid the machine shop and just toss all new bearings and seals in. I bought rings and the tool to gap them.
I also bought a digital caliper and some plastigauge. I'm kinda worried about the cam bearings fitting tight now that one was spun.
Ps. I'm gonna have to Google scope creep

This is what's happening, I I hope it's not harmful, lol

Harmful to the wallet.

I want that Truck Norris cam from BTR, but it's out of stock. Thinking about the Texas speed stage 2 truck cam, or the btr stage 2 truck cam.

I tried to pull the cam out while the lifters we're still in there, with the engine upside down, and it was binding up. After I puller the lifters out with pliers and probably destroyed a few, the cam was still not wanting to come out. Found the problem afterwards.
Extra wide cam bearing... Lol

I bet that motor had a tick. That's what happened to my 1st motor too.

It had 3 broken exhaust bolts so maybe they couldn't hear it over that, lol.
I just found some slag under the thrust bearing too.

Gonna take the block to the machine shop? At least for a hone and clean up?
My motor with the spun cam bearing. There wasn't a lot of mileage on this cam, less then 20k. It was a BTR stage 3 truck cam.

This wasn't done to my GMT800, but it was done to my garage in which I do all the things to my GMT800. Does that count?

I thought about making my own hot tank, I might call a machine shop,but the only ones I know of are kinda shady so I need to do some research.
I was gonna ask what cam you were running. I am leaning towards the btr torq cam, but I really want that Truck Norris, lol
