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

[RobsFreeland]

Today I made sure oil filter was on, bolts on pan torqued.
Put on timing cover, harmonic bal, air con belt, lifters and their trays.
Replaced knock sensors and reinstalled valley cover. Headstomorrow for push rods measure. Before and after pics.

Why did you pull the heads?

 

[RobsFreeland]

New cam,springs and I’ll upgrade the trunnions.

 

[RobsFreeland]

Checking the ridge in the barrel. Cleaned up the carbon. Was making a decision on whether to go all out and flat top pistons bearings etc.

I know I’m doing incandescent because on an 02 the circuits are a mess of polarities, making it confusing as f to try to solder in led bulbs. That’s why nobody does the 99-02’s. Otherwise I would have done blue leds long ago. I tried converting some extra hvac controls I had laying around and gave up, and I’m pretty good at that stuff. In 03 they changed and it’s easy to figure out.

Interesting. I didn’t realize there was such a difference. I had a few surprises with polarity on mine, but nothing difficult.

I did both of mine -cams, dual springs, hardened pushrods, vitron valve seals- without pulling the heads. It’s not necessary unless you’re replacing the lifters. Is was especially easier to do it that way on the one that’s supercharged- no need to pull that damn blower.

Yeah everything electrical on the 03-06 is way different than the 99-02. Even things like the cluster are different and I have very little mod options there.

Swapped put the ****** old street shocks for some bilstein 4600s. Very happy over all. Also had to change the belts and tensioner assembly

You lowered at all?

Yea 2/4 drop spindle kit. But I have the 1" spacer in the rear so 2/3

Which shocks rode better you think? I'm in the market for some.

How much difference in pushrod length from stock to your new pushrods? You think I can start it and drive to tuner?

Same question for me. Leaning towards bilsteins but the bell techs are so cheap (guessing there’s a reason for that)

Vinci High Performance sold me everything I needed so they’re the ones that determined that but I’m pretty sure they’re stock length. I have no idea if your setup requires something different. You need to ask whoever you bought your valve train from that question. Whose cam is it? What are the specs? What lifters, springs and rockers are you running? Just curious.

Cam is from summit, 8701-r1 , new lifters that came with cam kit. Beehive springs, new, stock rockers. By eyeballing size of lifters and springs seem to be same size, I thought I could stay with same length just upgrade to hard pushrods. I have pushrods measure tool, probably do today if I can finish torqueing heads.

Ask Summit. Oh wait- they’re worthless. Nobody to even talk to. I bought from a company with excellent customer service with someone who I could reach out to with questions, www.vincihighperformance.com since I wasn’t all that knowledgeable myself. Yours should be stock length but I can’t say for sure. I could call Roger Vinci and ask him but that wouldn’t be right lol.

So true. I realized if everything was the same then I could prob stay with same length pushrods, but I changed cam and lift parameters so the length of the pushrod will change . So I will have to check length and lash. Hit with epiphany or brick your choice. Thanks

1000% bilstein I hated the beltech shocks from day 1.

Finally got enough clear weather, and snow melted, to wash and do half a detail today. Ahh.. better. Sorry for the crappy pictures.
