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

[pwtr02ss]

I bet you can tolerate it pretty well from inside the cabin. You make it sound like you are running solid lifters on a high solid roller cam with a lash at like .030-.036 lash.

I'm gonna take it back apart and check each one. Put the appropriate rod length and fix it. It's the little things that bother us sometimes

Changed the rear shocks on thecopcar. Not hard, but contortions were required. Dunno if the consumer Hoes are that way or not but the rear sway bar ends are in the way of the lower bolts. Had to jack up the frame to unload the suspension so the bolt could clear. Tires stayed firmly on the ground.

The end links are always in the way of the shock bolts unless you change their location by jacking.

Good to know. Looking at the angle, I could imagine having the drop in the rear, but unmodified ends links causing that.

Spent another hour or so today modifying the Harbor Freight Ball Joint Separator and got it to within a 32nd of an inch when I decided to just cut the bottom of the ball joint studs off with a dremel. Then the tool fit and I started manually cranking it with a ratchet. Stopped for a moment, looked over at my daughter and BAM! It broke free and scared me senseless! Same thing happened on the other side but to my daughter this time! BAM! LOL

She changed the engine oil cooler lines and then went off to her volleyball tournament and won all the games with her team. Proud papa. Checked over the knuckles on my work bench and fiddled around in the garage and put everything away for the night.

Hoping to accomplish more on Sunday, have to pick up the bumper on Monday.

Got some center caps for the declass.......not a perfect fit as I expected.......I have a trick up my sleeve though.

I also have a set of black caps on the way too. I only got chrome to keep the PPV look

I'm interested to see what you come up with.

What did I do today. Well, checked pushrod spec. Was barely over .040 preload, in the center portion

So, the new 7.425 pushrods I had ordered, got it just to the bottom of the spec. Good news, they are 90% quiet through all rpm range. Bad news, should've ordered 7.450 and they would've been perfect. I'll see how long I can tolerate the slight noise

Basically, the BTR cam I put in it isn't consistent throughout. The 4 outside corners are perfect, the middles are right at the bottom. Long story short, when buying a cheap cam, check every single one

Trying to decide if I'm motivated enough today to install the new ac parts.

Summit sent me a drier that had the factory seal/box opened, so I'm just checking the vacuum for now...

Summit: I'm not happy with open box ac parts, especially the fkn drier!

I'd send that ****** back. I put one on a camaro that had been opened. About 45min into the drive, it froze, blew pressure release that sounded similar to a ******* bomb, the blew its load all over the engine bay and windshield. I'll never use a drier that's questionable again

next time. Next. Time

After work yesterday.
Stainlessworks 3.5" mandrel bent 304ss catback
Literally the only 3.5" exhaust I could find.
Muffler is only 3" and loud(which I figured)
Wasn't the right kit for my vehicle apparently. This wasn't made for something with a third cat on the y pipe.
Cut the ball and socket end off of the cat to where it's 3.5", then cut the 2.75" two bolt flange off of the new Cat-Back and welded the pipe to the cat.
Then realized the tip goes straight out the back so I cut that off and made it turned down behind the tire like the factory exhaust and definitely not putting a chrome tip on it. Prefer leaving the natural stainless but I might get fancy and slash cut the end of it later.
Definitely going to start looking for different mufflers that will fit to make it quiet again.

And this morning, opens up hp tuners and corrected the fuel trims from around +24(lean) with intake and exhaust, got it down to -3(rich) for now.

Damn, straight thru design. Def gonna be loud, especially when it burns in.

Yeah, they didn't advertise the type of muffler and I know on their website they don't sell any mufflers over 3-in, so I was wondering what they were going to do about that.
But straight through louvered is certainly not what I'm looking for so that will come off.

It won't burn in though. These guys use stainless steel packing inside their mufflers instead of fiberglass so it never Burns in or blows out or anything.

I’m looking for an inexpensive cat back but everyone has the 10-13 style flange. Nothing for my 08.

Cool color

Oh is that the year they changed it over?
This wasn't inexpensive. Over 800 bucks but it's all three and a half inch mandrel bent 304 stainless.
Should give me plenty of flow for when I slap a cam in it and put the Whipple on top.

I believe it’s 10 when it got changed. I have no desire to LTH on the truck. This is why I was looking for a cat back. Just to add a little something.

I would love some long tubes, but this ****** state only approved some shorty headers so there's really no reason in changing out the manifolds
