that be awesome, thanks.

[menace121978]

hope this works... In case it is hard to see, the lettering on the 6-pin plug that goes into the switching valve is, from left to right on the diagram, F E D C B A. F is not used.

This drawing uses a generic on/off/on type switch. But for the factory switch, the wiring is:

A - Black (Ground)
B - Gray (Right Pump 12v)
C - Tan/Black (12V in to switch, to power pumps)
D - Tan (Left Pump 12v)

Holy crap my brain is in overload mode and I have made list after list of what I need to get in order to get my 6.0L swap going. Great thread and awesome truck!!!!

Any news on the swap book?

Hi Bob;

I know this was an old post, but do you remember if the primer you used was a special engine / high temp primer, or if it was just regular metal primer?? I'm asking because I want to paint my engine but I can't find any high temp primer in the stores and I don't know if it is necessary or not ---- although I would think that it would be important to use if it was available.

Thanks!!

Gordon

That is the same hole I used for the temp sender. The original adapter I bought from S&P was a POS, so a fellow board member made me a couple that are the bomb:



With the POS adapter from S&P:



They work great! I had a small leak from the beginning, it seeped between the adapter and the sending unit, and it would drip onto the manifold. Not really a big problem, but man oh man burnt antifreeze stinks bad! So when I was finishing up the A/C I pulled the adapter out and used pipe dope between the sending unit and adapter, and between the adapter and the head. No leaks now!

Those adapters look great. Where can I get one? Are the stock gauges electrical or mechanical?

Hi DJW32,
I actually made these adapters for Bob/Fred. I had some fall off scrap pieces that I made these for a few board members. I could make more if I had the material. C360 or C-3600 free machining brass hex stock.
Also, he used the oem style gauges electronic from an 88 up burb I believe.

Glock, do you remember where the speed signal goes? The speedo has 3 inputs if I remember correct. I am putting a LQ9 in a military blazer and I am going to use the 91 cluster I have but I am unsure which pin to put the wire from the computer to. Is that all I need to do once I figure it out for the speedo to work? I know I have to repin my plug to match the 91 and I am switchind to a 91 tcase with the vss.

I had swapped out with a Blazer cluster when I did the swap, but the trip odometer didn't work. I had picked up another speedo with a working trip odometer and it showed fewer miles, but had been putting it off and finally did it today.

So.. I got the "new" speedo installed, and it works, trip odometer too. Also got the other steering wheel on, and I like it MUUUUCH better.

I had to get up in the attic of the shop, and found the new deep trim rings that I originally bought for my 68. So I pulled the OEM shallow ones off and put the new deep ones on. It looks real good, and adds some more shine to it.

It's been pretty straight forward so far, I really thought I would have a lot of questions and have things stump me since this is the first time I've ever done something like this. But all the planning has truly paid off! I really do think just about anyone could do this. There is a LOT to be done, but it's not nearly as daunting of a task as I originally thought it would be.

The speedo, and entire gauge cluster, is sourced from a 90-91 Blazer, Suburban or dually. The one I got is out of a Blazer. The electric speedo only needs one output wire fed to it from the PCM. When I got the cluster, I followed every circuit from the pin to see where it went, and made a drawing of the connector on the cluster and noted each pin and where it went. Today when I pulled the original cluster, I did the same thing noting wire color, what is was for, and what pin # it was in. Then I made another drawing of pin numbers, and where I needed to put each wire for the new cluster. The original cluster had 3 ground wires running to it, the new one only needed one, so I cut the other 2 off. That gave me a wire/pigtail I could use to run the speedo output wire to and put it in the right hole on the connector.

How did you figure what was a ground and what was hot on the 91 cluster? That is what has me worried as I don't want to smoke the 91 cluster. You still got the drawing?


EDIT: I found this thread with a excel ss with the pinouts... he left off which one was for the speedo though.

Good reading here.

Where you at Bob? You need to pop in every once in a while to let us know you're all right.

Any chance you would be getting some more stock around?

Occasionally some is on epay. I haven't checked in a while. To answer your question, maybe, not sure. We haven't had to make any parts that leaves the fall off behind.

It doesn't need to be some hard to come by material to work. We used plain old brass for machining many different fittings & bushings and it works well. Much stronger than the same part made out of aluminum would be.

Onlinemetals will sell you just a couple inches of material if that is all you need. They will custom cut it to any size you want and the price gets cheaper the more you buy.

Hi guys,

I love this tread!!!

It's got me all wired up about doing the same with a small twist; maximum mileage!
My '86 swb has a 400sbc/700r4/2.74 combo right now.
With gas prices here in Europe around $ 8,- per gallon I want a combo I can drive as fuel efficient as possible. (I Loved the power and mileage on my old '98 LS1 Z28)

I don't push my cars hard, so I'm still thinking either a 4.8 or 5.3/4L60e combo.
I guess I'll go the Fred route,altough maybe a lower rearend? Like 3.08 or 3.23 or so with max. mileage in mind.

What's Fred's average mileage since the LS build? I only read about the mileage during the build.

If there was a place I could get all the parts needed for the swap at once.... That would be it for me since there are no 5.3 pullout combo's for sale here in Europe. Oridering every part bit for bit would really kill the deal for me....

[monte0185]

Man this is a long thread. Took me a whole day of work to read this. I love my job!!! I like a few others on here have Fred's Twin and have planned pretty much the same thing only Im going with a whole different suspension setup. I talked to nate and hes in the process of setting up a coil over front end and I think im going to go with a 4-link rear but after seing that ladder bar setup that could be interesting too. I figure a 5.3 should be plenty as my 05 suburban had one and it pulled my 16ft trailer cross country several times no issues. Lighter truck ought to be better. I appreciate all the great info this thread gives and cant wait to see what you have planned next. Here is a pic of my truck.

[ronnieb]

Glock are you out there?

This is a wonderfull thread, I have read and re-read several times and catch something new each time.

I have an '84 LWB completely restored but still has the 305/700R4 combo in it. I have finally assembled all the parts and a 5.3/4L60E to start this project. I do still need to send the harnes and computer in for mod to standalone.

I have one question right now with probably alot more to follow in the future. You made an extension to frame mount on the pass side to support the new motor mount location and mentioned you would make a template. I will be doing the samething to mine but can't find the template, but I'm guessing from the pictures that you added about 2-3 inchs to the mount?

[STOCKISH]

Dern Bob, you havent been on here since October 10th. I hope you are just busy with work and family. Hope all is well with you brother! Hope to talk to you soon!

Bump
