Sorry if this is a repeat thread, but I tried searching and couldn't find exactly what I wanted... I found a 6.0 from a 03 escalade esv, low miles, good price... Now other than a tune, what exactly do I need to put it in a 02 hoe 4.8L? And even though it came from a truck with awd, will it bolt to my 4wd Trans? Again sorry if it's been covered and I missed it, I just.don't want to waste my money...and I need to start buying anything I'll need for the swap.

It'll drop in BUT you should use your 4.8 intake so it's completely plug & play. Trans is fine...get a tune, might want to get a performance torque converter since you'll have the engine out, check motor for leaks (intake, oil sender, oil pan gasket, check for corrosion on the knock sensors, etc), & for peace of mind maybe replace the water pump.

The black plastic intake is the plentum. Hes saying that to make it easier for the wiring harness and injectors to not have to mess with new connectors

Yes the 6.0 should use bigger injectors but I'm not certain how much bigger they are. If I was to do it I would use the intake and injectors that come on the 6.0 and if your wiring harness doesn't work with those injectors they make a pigtail adaptor for swaps like that so your harness will plug into the injectors

They are the same injectors. Only 8.1 and flex fuel are different. Same intake manifold as well.

Yes, recommended that you use your 5.3 intake and injectors.

Not just intake, the injectors, alcohol sensor, and fuel pump. However injectors from a smaller engine are not large enough for a 6l with e85.
Also depends on what vehicle you have.

Is it possible to do the swap and keep FLEX??? Also, is it possible to buy a newer 6L w/ active fuel mgt and have it programed for my vehicle???? Currently have an 03 5.3 W/ Flex

Yes it is possible to keep flex fuel with the swap. Go to bigger injectors. It is not possible to run active fuel management without piggybacked computers. Lots of work.

So should I keep the stock 5.3 intake and run the 6.0 injectors??? sorry to ask so many questions. And thank you so much for your help!!!

Nope, flex fuel injectors are larger than 6.0L injectors, but are not big enough to run a 6.0L on E85.
Could get fuel injectors off of a flex fuel 6.2L.
