First it was the 4L60E that bit the big one...working several states away and was unable to deal with it myself, so had to pay a shop to do it for my wife. Then the cats plugged up. Wasn't able to get the issue dealt with right away, so the wife drove it making a hell-of-a racket that way for about a month+. Managed to get a set of longtube headers and had a buddy install them for me...still several states away. Once the headers were put in, the worst of the noise was gone, but a new sound was coming through now. Stethescopes had the noise coming from in the block. Great.
Well, I don't have the time to yank the motor and do a build, and I don't have the room (or time) to get a block and build a motor, so I'm looking at a Reman LQ9 and stuff it in, making a trip to where the Avvy is and in a weekend work blitz getting the 6.0 swapped in. I know there are several threads on this already, but they're old, pics are gone, and apparently responses to them aren't going anywhere, so I thought I'd start my own thread on it, so here goes:
***I know that the computer will SORT of tune for the bigger engine, slowly figuring out the new parameters needed and will pretty much work. I worry about the built-in tune of the 5.3 trying to pull that DOD nonsense with that motor. Will just running it in trailer/tow disable that? Is that ALL that trailer/tow does is disable DOD? If not, what else does it do?
***Going with a complete crate motor, I don't know if it has a balancer included or not--if not, will the 5.3 balancer work? I will be swapping EVERYTHING from the 5.3 onto the 6.0 longblock.
***My 5.3 is the L59--the flex fuel motor. I understand that it therefor already has larger injectors? Will those injectors be sufficient for the 6.0 then?
***I MAY bite the bullet and actually get HP tuners, first time using it in the Avvy. Would be obviously disabling DOD, ignoring the rear O2 sensors, what else would I want to do?
Help here is VERY appreciated. I'm trying to get all my ducks in a row before pulling the trigger and buying the motor. After core and tax it's <$3200. I don't know of ANY supercharger kits that are anywhere NEAR that cheap, and with also the issue of the STRONG likelihood of a spun bearing, I don't have the time to mess with the 5.3. It's the perfect time to upgrade, hence why I'm so serious about going with the LQ9. The same source for the LQ9 has the LQ4 for only $70 less, so the LQ9 is the way I wanna go.
