6.0 Swap Time!

[Sam Harris]

Awesome. I'll absolutely be going through you then. I appreciate all the help and advice everyone is sending my way.

HIGHLY recommend @BlackBearPerf !

So my 6.0 Swap is finally done! For someone who's never done this before, I think I did pretty good. Only issue I ran into was I forgot to put the metal gasket between the passenger side exhaust manifold and the exhaust pipe. Easy fix.

The difference in power is unreal, even without a tune. Still, I don't want to push my luck with it.

No codes, no problems. All the other issues I had with the 5.3 are gone! No more perpetual knock sensor code, no more valve tick, no more oil pressure gauge going haywire. I am so relieved to be ALMOST done with this swap.

Now I'm just waiting for my tuned computer from Blackbear Performance to really wake it up. I couldn't have done it without the help and advice you guys provided me. Thank you all.

On an unrelated note, another problem has reared its head. It seems the slip yoke on the forward drive shaft is making a horrendous clunking noise around 30-40 MPH. It moves quite a bit if I grab it and twist it. I'll post a video of what I mean, but this problem has been driving me nuts since before the swap (Honestly thought it was rod knock in the old 5.3). I tried greasing it up, and that helped for a very short period, but it seems like it may need to be replaced. Any advice or ideas?

I returned mine starting from LM7 baseline to LQ9 using HPT. It will run otherwise. But will run much better with an appropriate tune.

You can segment swap motor stuff from a LQ9 engine as well. I however started and tuned on my own.

So the 5.3 tune will have different specs for the injectors. You will have to use the 5.3 intake, fuel rails and injectors on the 6.0. Not a big deal, and it will let you drive the rig till you get a tune.

So far as I know both LM7 and LQ9 use the same 24# injector?

does not seem like a lot of play to me, you might have to jack up all 4 wheels off the ground, run it and see if you can determine the source of the noise

I'll take a look at mine later today when I'm under there, to see how much movement is in mine compared to yours. Is the clunking noise coming from the T case or from the front diff?

His first post said L59 so I went with that assumption. And they do have bigger injectors than the LM7 and LQ4/LQ9.

The only difficulty it seems i will have is finding an engine hoist tall enough to remove/install. It has a 7 in. lift.

Remove the wheels and lower the vehicle to some blocks.


Update, I see you already dud the engine swap. I'm late to the party
