Its a 2006 GMC w a 4.8L and he is wanting to do an LQ9 swap. Correct me if im wrong on these
1. A LQ9 would be an easier swap because he has a 4L60e and the lq4 was mated with the 4l80e.
2. Will everything swap right over? Engine Harness, fuel lines, engine mounts? I believe they will all work right?
3. This should be a fairly easy swap right?

Be sure to get a 2002 or newer 6L to get the LS1 size crankshaft end. The early models had a longer crank and requires a flat flexplate, not dished. Also, double check the bolt pattern of the flywheel to the converter before it goes in the truck, if you have to rework the holes in the flywheel to mate up to the converter, its so much easier to do out of the vehicle. That or just use the flywheel off the 4.8L engine.

should be easy, just use the 4.8 flex plate, front drive acc and harness and put it on the 6.0 and shove in the truck and
If he's getting an LQ9 like the original post said he won't have to worry about having an old style engine with the longer crank snout.

Gotta update the tune, too.

OK it seems like it would be fairly easy, next question.
Anyone know where I could get a used one? My friend has the money and is dead serious.

PM Kurt and get the # of the salvage yard that he's all the time saying has 6.0L engines for sale. You might call Hi-Way Auto and see if Austin has one, too.

OK if we were to do an lq4, what all would need to be done for the tranny?
I found this?

Steer clear of ebay engines unless they're local. You can get screwed royally on one. LKQ is nationwide. Call them for local options, or Greenleaf salvage for national options.
