First post here. Came from LS1tech. Got a couple questions for you all. I got a 4.8 L20 flex fuel Silverado and was wanting to know what all is need to go to a L96 6.0. I was under the impression that all i needed was the L96 long block, and that my intake/fuel system/accessories from my 4.8 would swap over. But now i have been told that my 4.8 intake wont work with the l92 heads that come with the L96. Its that true? Also, what about the fuel pump/injectors/rails? So are the 4.8 flex fuel injectors/fuel rails the same as the 6.0 flex fuel injectors/fuel rails ? I figured my fuel pump would be fine also, am i right about that? And i am assuming the accessories should bolt up just fine. Am i missing anything? The L96 should just be a plug and play then retune right? Also, anyone know if the lq4 would be a plug and play in a nnbs Silverado? My cousin keeps telling me to go lq4/9 because its stronger, but i don't think it would work because its a genIII engine. Anyone know how much a 2012 4.8 with less than 8,000 miles would go for?

 

Holy crap that is a lot of questions bundled up.

LQ4/9 will not work without changes.
L96 is direct swap if you get it as a complete motor minus acc.
Its basically the same as doing a 4.8 to 6.0 swap in a gen3.
Your fuel pump is fine...injector size is diff i believe. Intake from 4.8 will not work on.the 6.0 unless you swap your heads onto the 6.0
The L96 has vvt so you got to decide what you are going to do with that. Best to do w.e while the engine is out vs in the truck.

 

I know lol. I should have numbered the questions.
I was planning on getting a vvt delete from texas speed or some similar place and then doing a cam with valve springs before the engine goes in.
Whats a good price for a l96 with 10,000-40,000 miles?
