Going from a 5.3 to a 6.0, Any Changes Needed?
Hey guys, it looks like I found a smokin' deal on a 2005 LQ4 6.0 long block. My plan is to swap everything from my 2005 5.3 (sensors, intake manifold, injectors, PCM, etc). Do you guys see any issues doing this? Are the injectors the same between 5.3 and 6.0 LQ4's? I know I'll need a re-tune to make everything run decent, but other than that am I missing anything?
Thanks guys!!
Thanks guys!!

I figure using GM MLS gaskets with a thickness of .055" I'll still manage at least 10.5:1 if not more, agreed?

They were aree still used with the 4l80's. You can tell by looking at the rear cover and if the crank is flush with the cover its not installed if it sticks out then it has one.
The all 5.3l stuff will swap right over.
