Rebuilt or just heads?

No coolant in oil. The truck is in excellent shape. Maybe we can do the motor now and transmission later this year. Would we have to do anything with the 4x4 transfer case or just the tranny?

4L60E transmissions are a crapshoot after 100k. You got 210k out of that tranny so it doubled its life expectancy. Yiu can find a decent junkyard 6.0 for about $1000-1200. And then do the tranny.

I talked to my local shop yesterday. He told me that if I pulled it out and took it apart, and took it to him for the work, the cost with parts would be around $1500. That doesn't include an oil pump or timing chain, which I might want to replace, not sure. I guess I could add a performance cam while I'm doing this too. From a little research, it looks like I can get a remanufactured one for about $2200.

 

I don't think I'm going to worry about the tranny right now and if it goes, it goes. But for now it feels good. I don't think I want to even talk to my son about the 6.0, even though he would love it. I've been reading you can expect about 12 mpg, lol.

You definitely want timing chain and oil pump, I would guarantee that the chain is bad and changing the oil pump is just cheap insurance.

Ok guys, here is where I am with this project. I have pretty well decided to put in a crate engine from engineguy. They are about $2200 including shipping and have the oil pump/chain and a 3 year/100,000 mile warranty.

Good idea getting one with a warranty. Around here Jasper's are a big deal cause of the 100k mile warranty. Have to see what they allow as far as modifications.

 

As to MPG with a 6.0 you probably wouldn't get much of a drop. If the price for the 6 liter crate is the same as a 5.3 I'd get that.

I talked to my son and I'm pretty sure this is what I'll do and a couple of questions. His engine has about 220,000 and less than 40 oil pressure on the highway, so no way I would just put heads on that. I was going to just get a remanufactured 5.3, but for about the same price, I can get an 01-07 LQ4. So, I think that's what I'll do. I know it will stress the 4l60e tranny (he has a vette servo in it), but oh, well. A new 5.3 will stress it a little too.

 

My questions - does it have to be tuned before being driven and who best to tune it? What is the turnaround on sending my computer in? Also, should we put the electric fans in while we are at it? And it's okay to use the 5.3 intake, right?

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
