If she had gotten off on time, I'd have already been outside. As she just left work, it'll be a minimum of 45 minutes. All good though, sitting in the recliner watching toy story with the kids in the meantime.

Sounds like you are practicing good life/work/'burban balance. :0)
Listen, if you don't give up on your machine, when your kids get to the
right age, you can have them help you like my twin daughters helped me:
Spreading the blame for all the noise - each daughter did 1 piston, so in total they were 25% responsible for the resulting side pipe cacaphony

My 6 year old and 4 year old are both interested. At least for short spells of tinkering where they can spin the ratchet, and reach. Now tearing floors out of going in the crawlspace for something, they are both all in. They especially like looking for our 'pet' black snake that lives in the crawlspace. Free rodent control.
Apologies for the delay...going from read-only lurking to a contributor I'm
still learning how to navigate back to a discussion already in progress. Got it.
Before we discuss your plugs, let's take a look at what I don't see:
1st example: 1 very bad oiling cylinder (#5), + 1 darker A/F ratio(#8), + 6 more or less the same. It will take more than a tuneup to sort this out. (!)

On multi-cylinder engines, Sesame Street taught me all I needed to know about troubleshooting: "One of these things is not like the others!"
2nd example: 3 good A/F ratio, 3 fouled from too rich mixture:

From a Jaguar website, owner asking for help. Once you open the bonnet & discover that there is not 1 but 2 carbs feeding the engine, the recovery plan snaps into
sharp focus.

OK, using those 2 photos to give us some context, I'd say that your plugs
are in really good agreement overall. Given the coloration (and lack of oily
deposits on the threads) I'd say that you have a solid V8 foundation to
work with on your 'burban!
Fine points:
* #8 plug is slightly darker than the #2 plug. Given all the uncontrolled
variables we discussed previously, I wouldn't chase this just yet, and
instead wait until we read the plugs *you* installed after some miles
have accumulated & revisit?
* If you look at plugs #1, #3, #5, & #7, you can see the shadow caused
by the SBC plugs installed at roughly a 90-degree angle to the cylinder
they light off. In other words, only half the porcelain sees the color
of combustion.
The only reason I point this out that if you take a close look at these
& visualize how the center electrodes are 'clocked' in their respective
bores...and then you go off & read about how some racers** go
to great lengths to 'index' all their spark plugs to face the same way,
now this should make more sense. (Warning: These are
fanatics chasing every last erg, but if you read around enough you
*will* see spark plug indexing discussed.)
* Given your oil analysis report, I was looking closely for a
too clean (steam cleaned) plug, but nothing stood out. For
now an oil change to go along with your fresh set of plugs
and again we'll keep an eye out for this down the road.
How about that -- some good news about the 'burban
you're debugging on a Friday evening. Compared to
the 2 other engines we compared your engine's plugs
to, you should celebrate your good fortune! :0)
Good luck prepping for your upcoming trip --

**And also Honda, in all places the 2-seater,
3-cylinder, 70mpg Insight from the early '00s.
In the shop manual they specifically wanted
the mechanic to maintain proper spark plug
indexing for max efficiency, and in order to do
this they listed spark plug numbers with suffixes
A, B, C, & D, each providing a different center
electrode clocking. (!) Yup, the very first time
gas went up to $4/gallon, I bought a well-used
Insight, put a bag on my head w/cutouts for my
eyes, and cut my fuel costs back down to
<$2/gallon vis-a-vis feeding the 30mpg base Civic
hatchback I was driving immediately prior.

long commute...you gotta do what you gotta do. :0)

Thanks for the feedback and confirmation of my thoughts. #8 was also a major PIA to get to with hoses in the way for rear heat. Wouldn't be surprised if it was skipped last plug change.
I came across some discussion of clocking the ground electrodes while lost in a rabbit hole. Not something I'm overly concerned with at all.
As for the trip, maybe you've got me and @South VA confused on that front.
Good call -- given how some view auto maintenance, it's quite possible
this explains what we're seeing. This is the kind of thing where I learned
to take anything I saw from other people's plugs with a grain of salt. :0)
And we're in total agreement on indexing the plugs. I wasn't lobbying
to implement that. (Especially in a tight engine bay, what a PITA.)
Instead, your photo just made it really easy to see so i simply remarked
on it.
And yeah, oops -- I must have mixed in the comment where the poster
was going camping on the 7th, claiming he needed the positive tension
in order to fully get into the repair groove.
Anyway, I think you're good to go in this area -- looking forward to
your next update.
Cheers --
I'll admit I didn't think of the plug orientation affecting the coloring pattern until my second look at them.
Other projects claim my time and effort for the coming weeks unfortunately.
No worries! Despite my excitement with my new (to me) C2500, work progressed
in fits & starts over the past year -- way too much life intervened & demanded my
time & attention at a higher priority.
While you are away we will find other windmills to tilt at. See you when you return.
Sincerely,

Haven’t made any progress or even worked on the suburban since changing the plugs out. Did drive it to town yesterday for groceries and fed it. 7mpg rounding it up touch the last tank. Thought that the fuel receipt was painful enough then groceries and losing the a/c made it more so.
Anyone know if the compressor clutch can be replaced without opening the refrigerant system? Haven’t pul the belt to check if compressor has seized yet, maybe one evening this week. Photo taken after cycling a/c switch on momentarily then shutting down the engine.

Ooof, rough day bud. Clutch should be replaceable on the truck. I’ve done a couple on Hondas and Toyotas.
I just don’t know if you can find just the clutch anymore though…
