Well, I was going to say, if we ever get to my farm, it can be muddy, and we could set up a shooting course, and Ken and Tex could square off...
So on the Burb, Monday morning remains the time when this thing gets thrown into the chock blocks. The chock blocks that this runner uses to take off on the rece. I am hopeful that everything can be wrapped up in a quick bit of time and possibly get it out on the road for some son/dad time.

Haven't checked. Not a transmission shop. Gen mechanic like Ken
Doing Trans leak and AC problem.
Had to work all day yesterday moving a friend out of his old home into another one. 9 hours of, well, you know how that goes.

My pre-Rangers were magnificent. They worked all day long, and hard and never said a single word to complain and easily outworked every man there.

Am strongly considering it JR. But first let me put some miles on it. I'm thinking I could get a good price on my super clean and lower mileage 6.0 and 4L80E... And I stumbled across a rebuildable LB7 for $700 not too far away.

So update is: Parts on order.

Troy is replacing the front double seal on the transfer case. I guess I must have buggered it up or something. And I never looked at the transfer case autotrac fluid to see if it was the same color as the trans fluid is. But he concurs, the only leak he can find is at the mating of the cases.
As for the AC, he didn't get far enough into it to give me any answer, but thinks it is the climate control motor like Ken suggested. He actually has another 6.0 truck in the shop with the identical problem.

Not saying I'm doing it, but I'd want a LML mostly because of the much better transmission, if that is possible

But having just looked at the prices, my immediate inclination is No Freakin' way!

So to convert a harness is like $600

I'm guessing a Duramax engine and Ally is not free. So a good running set with low mileage, what $7K-$10K???

And if it's one of these engines loaded up on miles, then I'd go through it and that, also is not free. Guessing $3K on top of the acquisition price of the engine, and we all know the trans is $5K.

I saw a push button transfer case harness at $980!!!!!!!!!!!!!!
the transfer case $1750
another EFI Live tune and switch $700
Then there's the Intercooler, radiator, trans lines, driveshaft mod, all also free.

So unless I miss the mark on this wouldn't I be adding another $20K to the investment?

I am a bit disgusted by the price that things have gotten themselves to these days, just outrageous!

I am actually happy from this morning's little exercise. It helped clear my mind of any such foolishness of installing one of these oil burners into the Burb. So, it will be slow, but then again, it does not to be quick, just has to get to point B from "A."

For a bit more than one tenth the cost of a D-Max conversion I should be able to add a turbo onto the end of some exhaust piping and double the output, and learn to be satisified with that.

After the very short drive yesterday, I was most dissatisfied with the gearing of the 4L80E. seems like you stay in first and second for an eternity, waiting for the engine to climb into a useable power band that I was not able to locate.

All this said knowing the tune I have is ONLY the starter tune designed just to get it running enough to be able to record data which leads to a useable tune. But, there is simply not very much power in there to work with, so whatever I end up with will just be an adjustment from my well tuned D-Max powerhouse.

what's the stall limit on the converter you got again? with the cam you threw in there and the better breathing heads I'm sorry to say I'm not really surprised, as these motors don't really even start to make decent power until around 4500rpm. you opened up the exhale portion of the motor a ton and a turbo makes sense as you now need to get more air in there, but off-throttle response would be better with a supercharger and the gearing you have in it. my 4l80/6.0 in the Yukon are the same symptoms as you. We rebuilt the trans with a 2500 shift kit for towing the trailer when we still had it, and it would stay in 1st and 2nd longer to keep the RPMs up, shifts hard too. now with the new motor there's more power since the old one had a failing cam, but still doesn't really start pulling till around 4500. turbo lag in the 6.0L might still feel like you don't really have much out of the gate, but a supercharger would be on-demand power, bolt on to the manifold without as much modification as plumbing a turbo in. just my $.02 sir. Maybe Ken or Shawn can chime in here.

Don, you seem to be judging aweful prematurely. Nothings broken in, not to mention the tuning. You could possibly be 20-80 horses short of the final product, not to mention that something could actually be wrong, which the tuner will probably catch. Be patient my friend.

Don. A cc/lb duramax is 75k. CustomiZed the way you have the burb is what 85/90?

You have what in the burb? 25/30?

So with a DMax conversion. You’re at 45?  Perspective my friend.

Not a bad deal if you plan to keep it and you have a rock solid base to start with.

I say forget doing anything other than the updated tunes and then wait a year and convert it.

You’ll be happy and you’ll never want to get rid of it.

Nice LLY will set you back 4k with refresh probably 6 (rings gaskets etc)

Built trans 4k if you r&r yourself.

Bits and pieces and harnesses 2-3k

Well, I am not going to do anything in the short term, to be sure.

As for keeping it, After looking at newer Burbs, I did the math and you are very close on the numbers. I think it would be much "Cooler" to keep the classic and update over time. I don't think I will sell it ever. I may own a newer one some day, but this one will maintain a spot in the upcoming barn.

And for the real progress report. The leak is gone. It was the seal in the input of the transfer. Call it me somehow, but I really don't know how I buggered it up, but I did replace it, and it was leaking like a sieve...

On to the AC. Now this one turned out to be very interesting. They found several things. First the electric fans were not coming on at all. They went as far as to check the wiring in the two plugs going into the computer. And guess what?? I placed the new wires in the correct position, in the wrong plug!!!

So those got sorted and we immediately got a engine fan number one.

Note: I was not there and am trying to tell this as best I can from memory after having talked to Andy, the freakin genius who found this. I think he said he had some sort of electrical engineering degree and dows automotive wiring professionally.

And the AC compressor is putting out ice cold air so that's all good, but there is some wiring mixup that they can't seem to solve. He mentioned that this setup would work great if I didn't have automatic climate control. But because I do, the fans will not turn off when the motor is off and the compressor clutch will not disengage.

So I need to contact the folks who sold this fan to me and see what they recommend. There is a hillbilly way to get it operational, to simply place a switch in the dash to turn off the fans, but I think that would be retarded. I or she would forget it and come out later to a dead battery.

One way to fix for sure would be to install the factory clutch fan setup again, but I already trashed that, but I could source a used one. I would like to try and figure out the electric fans before going back to the 20th century.

Message he just sent me:

"May have backwards, but green wire ground controls relays to run both fans, blue wire runs just one. Want to hook blue wire up to a coolant temp switch in drivers cyl head to keep it from overheating. Tried hooking up green wire to pin 43 on connector 2 to pcm. It ground controls the relay for the compressor clutch. Worked to kick fans on with air conditioning, but when truck turned off, system grounds through compressor clutch and keeps fans on and clutch engaged. HVAC is automatic controls w/o sunroof, 2002 Suburban."


Make any sense to anyone???

As it’s been said before, you’ll want to stick to an engine from the same platform/year (or very close) because of all the electrical tie in. Going from an lb7 to an lly or even lbz isn’t too hard, but they did change all the electrical in ‘03. An LBZ is like the holy grail - most issues sorted out and pre-emission. Get into an LMM or LML and now you’re dealing with emissions (which can, and would likely be deleted immediately), plus a myriad of electrical issues to sort out.

I thought I read somewhere that the SACS style injectors was the fix for the older trucks. If so, the $700 LB7 starts to look like a pretty good place to start if a guy wants a diesel powered 2002 burb. If you’re not happy with the 4 speed and staying with gasoline power, what about a swap to 6 speed? Cheaper than building a Duramax even if you did start with a $700 block.

Well, I hear that the six speed swap is either near impossible or very difficult to sort. Besides, a turboed up 6.0 would work better with long gears.

Bottom line is that this discussion is academic only for the time being. I only want to get the engine in it sorted and providing power to get this Burb moving.
