If I go with the 6.0 (highly desirable) we will need a tune for the 6.0 to 4L60E trans.
Who in GA local does this stuff?
-
Man I'll definitely be watching this! Goodluck!
-
Tim Kirk has the tools to do it. He can also get you the engine/transmission from the LS guy who shares garage space.
-
Vengeance Racing are the LS gurus in GA
-
Proline in Ballground
-
Interesting, I'll be following this too... I had the 6.0 in my 1500HD and wasn't all that impressed compared to my sons 5.3 in his 1500.

My post left. Vengeance is in Cumming, but I know another place that's building my ls3/416 ci that's speaks ls like we would English.

Tick performance. They are sponsoring the build.

The engine swap is pretty simple, the tune will be the hang up. I would make sure ahead of time that you have someone willing and able.
-
One thing to look out for is that the ECM and the TCM are for the same model year. Apparently there are model year changes that can make things incompatible.

thinking hard 6.0. reding a lot of guys that drive daily and tow... no more down shifting on the hwy hills/mtns when not towing, super quick, same mileage, etc.
@PHANTOM I have a guy that can tune my box, or send us a brand new one tomorrow. I'll send you the info.

Will you still use the 4L60 behind the 6.0? Isn't that the main drawback to a half ton chevy tow rig?

Might be, I have 289k on mine and towed 10,000 a lot... over the Rockies at 267k. A new one will go in with the mota.
-
Doug, why not find a 2500 that wants to give up its 6.0 and 4l80? wiring and computer are there.. no tuning issues.. better yet.. find one with an Allison and make it interesting //SLAMIN//
-
Frame couldn't handle the Allison.
I thought the 2500s had a bigger motor.
6.0 works with same harness, only need simple program for 6.0 w/ 4l60e combo. Everything bolts on. Easy swap.
I want a 3 year/100k warranty on motor and trans. No worries.
-
4l80e would like that 6.0 a lot better. It's the same thing as a th400 but has an OD. I have a built 4l80 running behind the 416ci.
-
4L80e is quite a bit larger and can cause fitting issues if the tunnel is too small. I'd stick with 4L60e for bolt-in.
-
Honestly if your putting a new stock 6.0 in the place of the 5.3 it will be really simple for any good LS shop to flash your 5.3 pcm with the 6.0 information. If you got the extra $$$ I would put some long tube headers and y-pipe too. Maybe a tow cam if it will not void your engine warranty.
-
Thanks guys. This is a 11 year old vehicle that will probably end up at a University in the next couple of years, and it's not a race car, so I should be good with a 5.3/4L60E. Still exploring the 6.0 though.

I thought the 4l80 came with a 6.0 and the smaller trans with the 5.3. I'm not saying anything about racing, but the fact it will handle towing and engine power a lot better. A stock 6.0 with a tune and very mild cam could easily put down 400hp. Not sure on fitment but I would always prefer a bigger trans instead of working a smaller trans harder if it fits.
-
I know it would be awesome. I just don't have a need for any of that unless it cost nothing.

im with Tripp all the way on this one.. the size difference cant be much. the older 1500s and 2500s were built on the same chassis.. I had a 2002 with a 6.0, 4l80 combo. I think a crossmember and a driveshaft would be all ya need, the lenth is the only size difference right Tripp? Not to beat a dead horse here..

Not sure without pulling a Google search and it's my bed time because I work 3rd shift now. The only concern I see would mainly be around the height difference or what small of one there is. It's nothing to shorten a shaft down and no need to buy a new one if it's a little longer.
-
Thanks guys. All great suggestions if that's what you want, but not for me.
Only options for me are:
- 4L60E replacement immediately . and 5.3 or 6.0 later.
- 5.3 and 4L60E replacement now
- 6.0 and 4L60E replacement now
All are 3 year/100k warranty
I've had it 10 years and it is immaculate. Worth nothing trading. 289,000 miles. Original everything. New Michelins, etc. Trans is done, so a repair is required. Motor is weak, and letting out a puff on start occasionally. Worth more to me than anyone else by far.
It's a family vehicle, may never tow, transports wife and/or teenage girls. I could buy a new 2500 or truck or tow pig, but they aren't my style for a DD. Prefer comfort, quiet, seating, back inside storage of the SUV.
We have a 4x4 surburban as well.
I'd have a duraburb if I thought I could justify the cost.
-
Does it have the 5.3 or 4.8 in it now?

you and me both!

5.3 to 6.0 conversion
-
well now I feel like an idiot lol. I just looked at the thread title...
-
Can you get an engine with that warranty other than as a crate engine? If not, then the engine won't come with accessories, so the cost will be significant just for the engine both in parts and labor.
If you go with a "raw takeout", which is what the guy Tim uses, you get a complete engine and its mated transmission and ECM. He warranties it to run, and the entire assembly delivered will range from $2500 for a modest 5.3 to a lot more for an aluminum block Corvette engine. Lots less to go wrong in my view. The only ECM work, AFAIK, is to put your vehicles VIN into the ECM memory. Obviously the engines that go into offroad swaps get a lot more work done on the harness and ECM.
That said, 5.3 engines are for the most part damn reliable. In your shoes I'd just rebuild the transmission and have the engine tested.
-
Just curious but what makes a stock 6.0 more appealing building your current 5.3. It would seem most engine builders would give you a warranty on your rebuild motor. even if you upgraded it significantly while you were at it. Would it be less expensive or no?

Everyone that has done the 6.0 swap RAVES about it. Same milage with a lot more power and it's a low cost swap comparatively to many others as you use same harness, ECM, everything bolts on, etc.
I'm looking at a WARRANTY build, national reputable service on motor and trans. 3 years/100k. Different arena than a custom built shop motor. A custom build is completely different, by a single shop guy or a speed shop, or custom builds/tunes.
-
Gotcha. In stock form is the 6.0 a huge hp & torque improvement or are you planning on adding performance modifications? I know my father-in-law has one in his 03 2500HD but he only gets about 9-11 mpg depending on city or hey mileage. Sorry for all the questions I'm just super interested as I have a 03 z71 in beautiful condition but it has 205,000 miles on it and the original 5.3/4L60E so I could possibly see doing if either ever went out on me.
-
Yeah, stock, just Google it and you will find a lot of folks have done it and love it.
I'm leaning 5.3.
Wife will drive it most of the time and
I can sleep in the suburban on jeep trips if I tow so am leaning away from the 6.0.
Cost is a factor as they won't give me core credit for the 6.0 and I have to have it programmed so the cost is considerably more. 30% more.
-
A tune is around $300 for a non dyno. Externally the 5.3 and 6.0 are the same. Could get a long block 6.0 and swap all accessories over from the 5.3. Sale the 5.3 and not be that bad off on the engine, trans different.
-
You could also stay with the 5.3 and just mod it for some better breathing, headers, intake, cam upgrade. Still be as reliable as today with a bit more get up and go.
I can't imagine the 6.0 gets the same mileage. I had the 6.0 in my 02 1500HD 4x4 Crew and on a really good day with a tail wind down hill I got 11. Normally it was 9-10 and it didn't change towing or empty. Thus is why I now have a Jeep and traded in the pig.

If you go performance, you lose the low cost and warranty. I don't need it for transportation of teenage girlies.
The 6.0 gets better mileage actually everyone is saying because it doesn't down shift on the hills like the 5.3 does in a Tahoe. I'm sure gearing and weight are factors as well.
$300 tune is part of it. Core is another. Additional cost of motor is another. Can't justify.
Wish I could drive both a week and decide. //OLDSKOOL//
Still thinking 5.3.
Thinking I will get the trans fixed first, and see how the motor is doing over the next few months on oil, etc. Not a drop under since Allsouth replaced the rear main seal. Also just did transfer case seals, all O2 sensors, and the intake manifold gasket.
It DOES still have a cold exhaust manifold leak rear bolt broken off on drivers side. very common issue with these. Can't get to it, so motor comes out or head comes off to drill it out.
I was CRUISING when the tranny gave up 3rd and 4th.

This is what I would do Doug. Tranny rebuilt or replaced and see how the motor hangs...I'll bet it will do just fine.
I did this same thing with my old Dodge Ram. Trans went after 180K, the 5.2L motor was a little tired. Did a rebuilt trans and it rocked on perfect for me until I sold it about 20K miles later.
-
Well, I had decided to do trans only,
but the motor was very low on oil when I went to drive over to Allsouth,
so doing the 5.3 and trans.
