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

[Rocket Man]

Yeah 2wd is a no go. Any chance of switching out to 2wd/4wd selectable transfer case?

Yeah but it looks like a giant PIA to me. I'll just quit full throttle launches and enjoy the ride. I might even have BB modify the tune and disable full throttle converter lockup- it's enabled right now. If I was to do a conversion I'd just do 2WD and enjoy burnouts.

I like your style!

Yup....glad priorities are still being observed! On a side note I am asking only because I am considering a Vortech V3 centrifugal for my 5.3 Tahoe. I knew that the trans would go quickly if I didn't do anything to it but actually wanted to step up to a beefed up 4L80 or 85. If you go to some Land cruiser forums you will find that the 5.3 platform is a REALLY popular choice for swaps but everyone feels the 4L60 is not up to the task and they always find other options for the trans. Do you happen to have an opinion of the Vortech? I know you like the Whipple but are you aware of any negatives about what I am considering? Appreciate any feedback you share.

The. Vortech is a centrifugal blower so it's going to behave more like a turbo.just not the instant torque of a PD blower like a whipple or maggie. With a higher stall converter it will shatter parts too more than likely..

Did this today. Installed the LED brake light strip in the rear window and deleted the rear wiper. I still have to get the correct plug/caps for the holes. Don't forget to leave enough slack for the window to open.

Finally replaced the pitman arm (AC delco-pro). It was my second attempt, last fall i replaced the idler arm and idler arm bracket and failed with the pitman arm (also AC Delco Pro). I removed the sway bar which gave me plenty of room to swing my mini sledge on the pickle fork this time. I tried 2 and 3 jaw pullers but they would not grip the center link well. Removal from the steering gear was a breeze with my air tools. I replaced the sway bar bushings and endlinks with hard blue urethane bushings (AC Delco/Moog). WOW, it handles like a totally different truck, not like cornering a land yacht anymore. High winds dont blow me all over the highway anymore. Oh yeah, I also replaced the leaking oil cooler block off plate gasket, I hope that's all the leaking was from since the rear main seal is only 2 years old.

Even with all the east coast rust and 250k miles its still easier to work on than any Ford or Jeep I have owned in the past.

Rant: WTF are there so many damn sway bar sizes??? I was going to replace the rear bushings and endlinks as well, but the bushings are too big.

6.0l swap or 5.3?

6.0. I recently got a gen 4 6.0 I was gonna build for it. Guy I do side work spun a cam bearing in his 10 Silverado so we worked a deal for this gen 3 motor. We put it in a nbs cc last summer. Bored.30 over lq9, shaved heads, 234/277 cam, 3500 stall, and the speed engineering 1 7/8 headers. Basically drop it in and have it tuned. Picking up a e-fan harness this week for it also

What do you think it's putting out? Think your trans can handle it?

Not sure. The nbs injectors are only good for 26 psi. The tuner had to choke it down to keep them from cutting out. I have some gen 4 flex fuel injectors and pigtails I may swap in. They are good for 36 psi. The trans has maybe 3k on the rebuild. I’ll put a corvette servo in and baby it. I know where a 4l80 is sitting I can get for next to nothing
