I'm trying to swap my 2000 5.3 with a 2011 6.0 and need to know what I need as far as parts

I'd sell it and buy an engine that will actually drop in and run without some major changes.

That 2011 is a whole different gen and uses way newer technology compared to your truck.

The small list of major issues to tackle.

2011 is a 58/4x crank trigger compared to your trucks 24/1x.
2011 has VVT that you would have to delete and source parts to replace it with.
2011 has the knock sensors on the side of the block and not in the valley plate like yours does.
2011 has the cam sensor on the front cover and not up top like your truck does.


It's going to cost you alot more money and time just to make that engine work. It's a big hassle in the end. You are better off selling that engine and buying a LQ4 or LQ9 GEN 3 engine that will bolt straight in and run with a tune.

Probably better off starting your own thread.....but....what year is the truck? If it's 99-06, you really don't NEED to do anything as everything bolts up the same. A tune would help get everything out of the 6.0, though.

In short, you'd need a 2007.5+ GEN 4 6.0 engine from a heavy duty truck or a 2500 yukon/suburban. Or even a 6.0 from a vortex max truck that they made from 07.5-09ish.

Those engines would be a direct swap with the engine part. You'd have to figure out what you wanted to do about the VVT (variable valve timing) that a heavy duty 6.0 has because the 2008 5.3 computer/harness is not wired for that. I think the L76 engine from a 6.0 vortex max truck has VVT too but I'd have to look that up again.

Then of course whatever you decide you will need to have the computer re-tuned for the changes you have made.

If swapping to a 6.0 seems too tough you should consider swapping gear ratio's in the axles. Say it has 3.42's or something, you would want to step up to 4.10's to help it out. That too needs a computer tune to make it all work together again.

You need a 2006 or earlier 6.0.

Sell the 2011 one and use the cash to buy a LQ9; or, trade. You'll spend FAR LESS money doing that, even if it isn't revenue-neutral, than trying to get that later motor to work in your truck. Keep it simple, go with what fits and works and hooks up.
