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

[gooffeyguy]

Got the other head cleaned up and assembled.

I did a waaay better job on this one.

Now i think i better redo the other head so i don't have an imbalance or something anoying.


And i have one head bolted down.
Used tie-down straps to pull the exhaust manifold out of the way to get a torque wrench in there.

The degrees thing...
Stretching the bolt should make up for minor imperfections i hope...


And i miss my hoe.
It's cold out, and our other cars don't warm our butts.


Merry Christmas all!

Do these motors have torque to yield head bolts?

Any motors that I've had the heads off I've replaced the bolts with either ARP bolts or studs if I plan on running boost. They're reusable

Good luck. Hope you don’t get a leak.

Crossing my fingers lol.

I didn't go too crazy with the head cleanup, mostly focused on cleaning and preventing carbon from sticking.

Before installing, i did a slightly better job around the spark plug area.
I didn't grab a picture tho....


Getting motivated for more hoe work...

...Y'all do know this is a photochop, right? A buddy sent me a link to an app: "Suspension Master"

Sometimes, I wish it really was 'bagged.

Other head is on, first torque done @ 22ftlbs...

Getting motivated to do the fkn 90 degree and then 70 degree bs...

My engine oil priming setup, hopefully it works when it comes time...
Bought the little adapter for something like $8 on amazon.

And the heads are on, just the passenger side has not yet been fully torqued... in a few minutes the fun begins!

Your stance is perfect!! Your photoshop is not haha. I was sitting there imagining how much work would go into getting that low when I realized!

Ls 6 springs, new guides/ seals. Installed on 5.3 ls flex. Waiting for cam and trunnion kit. Noticed on springs they have white stripe painted on have no idea what that is for. I’ll have plenty to do when cam shows.

 

[Just Fishing]

other head is on!
did a check with a digital gauge, seems to be about 75 ft lbs for the head bolts
So i gave every one a once over for good measure... the back ones were the hardest to get a good angle gauge on, so it's a nice little piece of mind.

Now i'm going to tackle the front axle install...
yay my favorite part...

 

[Just Fishing]

Well...
Front axle is in.
Much easier with the crossmember out apparently!
