'90 K5 "Project Sanity" Sold 7/5/2018

Thanks. I have had it for a while, and Russel favored it over the stock rad so I went with it. I bought a couple of rad hose adapters from Jags that run, as well as a section with an air bleed and a sight glass so I can reliably bleed the air out. Russ says the PCM will run the fans, so we're gonna have one fan come on at 210 F and off at 195 F. The second one will come on at 220 F and off at 210 F. Hopefully that will work well.

Lookin good
I think Deb made a good choice on that grill! 
That is how my fans are programmed and it works great, my tuner had to use a base tune from an '05 that came factory with electric fans and tweaked it from there.
Looking good [emoji41]
I like it too, although my fave is still the round eyed set-up from ~74 or so. Bolting up the valance, adding all the new grill hardware, gluing on the bowtie and buttoning it up for real right now.
Hopefully more pics later, maybe of something other than the grill...

The quad lights looks so much better than the singles in those years!
Yeah I agree. I let my wife choose the front end as I had a round eye 70's core, a single light 90 core and a quad light 90 core. She chose the quad light core...
I ordered all the new clips, inserts and correct screws for the entire grill and bezel assembly. Best $9 I've spent, and this is the only square I've ever had with a screw in every hole for the grill and bezels. Most others have been cracked, missing, duct tape etc...lol
Got the hood catch adjusted too. It opens nicely with an easy pull on the release and pops up like it should without having to give the hood the old 'bump'. Way easier than lining up doors.

Good to know that recipe works well! Thanks. My 5.3 is an '06 that came with electric fans only...so from a tune standpoint Russ says it's easy. He will also be tuning out the same stuff you did. Tq management gone, pedal delay gone, VATS gone. Rev limiter set to 6000 rpm, speed limiter to 105 mph. I doubt it'll pull 105 anyways...
Did you ever come up with an AC deal that worked to kick at least one fan on when the AC was on?
Yes. It requires two mini relays (DEI 8616). Tap the compressor clutch circuit before it goes thru the cycling switch and run that to both of the trigger positives on the relays. Ground the other side of the relay coils. Then run a ground circuit thru each relay switch, ground one side and run the other to the main fan relay's trigger wire that comes from the PCM for each relay.
You have to use two relays so one relay won't back feed to the other whenever the A.C. is off and the PCM is controlling the main fan relays.
Bout as clear as mud right?
I see "blah blah blah flux capacitor". 
I'll show it to Russel though. He'll know exactly what you're talking about.

Lmao, yep Russell is the man! He has helped me out on more than one occasion.I see "blah blah blah flux capacitor".

hahaha, I've read that manual too Rene'!
My previous engine bar I had with the 350 wasn't going to work, so today I spent building a new one. I certainly didn't want the shock hoops unsupported...
Scoping it out I figured there was a nice path over the engine just a little behind and above the alt and over top the throttle body. I made a series of slices into the tube on either side of the engine so I could create a nice gentle curve.
Once it was clear the ends were going to land where I wanted them I welded up and ground smooth the slices and got the ends coped and cleaned up.
Not 0.0 on the level...
Then again the core support reads the same...
Next up before final welding and detailing was modding the floppy GM cover. Ended up looking like this, and as a bonus is no longer floppy!
I bombed it some random green I had here. It will eventually be the same metallic green as the hoops...
Next up is a small bracket to stabilize the Spectre cold air intake and keep it off the upper rad hose and the serp belt...

I like it! Nice work
that came out sweet...
Thanks guys. Not a lot of room to work with, it's about 3/8" above the TB. I do have the poly engine mounts so I don't think this is ever going to rock enough to make contact. The cover itself is quite flexible (and cheap) so I went with it. I like the overall look now that it's done.
Looks pretty damn cool, Rene. You know I always like to see the king doing some fab work. Nice way of getting the bend. Almost came out like my rear engine cage bar.
Did you weld the standoffs on the interior of the tube? Just don't see the weld..

Dude if you and Russel install a flux capacitor you gotta share info

The standoffs are too deep to get the gun in there. I used my 1.75" holesaw and my notcher to core out a pair of slugs from 1/4" flat bar. I had to dress them down a hair as well as buff out the weld seam on the inside of the tube...but got a near perfect fit. Then I put a 3/16" bevel on the slug, set it flush on the bottom of the standoff and burned em in from the bottom side. Even ground flush there is plenty of weld in that area.
Second to last pic you can see the heat marks on the bottom of the standoffs...if you look close.
