The vehicle is a 2000 Silverado Z71, with a 4.8L and a 4L60E. I want to drop at least a 5.7L into it, hopefully a 6.0L.

Just wondering how simple or complex a swap is with an electronic engine is. First off, can the 4L60E handle a 6.0L or even a 5.7L? Or should I get my hands on a 4L80E.

Also, is it a simple matter of swapping the motor and computers, or are extensive modifications required? I would assume all the mounts and vehicle harnesses are the same if the motors I'm interested in are factory options.. Thanks for any and all info.  Cool

As far as I know, most of the Gen-III and IV small-blocks are relatively interchangeable. You should be able to drop in a 6.0 Vortec pretty easily. I'd check out:

They're kind of the authority on engine swaps. I'm sure if you check out any GM-specific truck forums, there will be some guys that could give you some pointers on doing a swap like this. I found this discussion thread that might offer some helpful tips:

I was shopping around and discovered an late model 8.1L Vortec.. Any idea on interchanging a small block with a big block?  Cool

You'd definitely have to upgrade to the 4L80 for that, but anything is possible with enough time & money.  Smile

If the bellhousing pattern is the same, it should be no problem. Generally, swapping the engine & trans together makes for the smoothest swap, but you could probably do them separately. What MY is the 6.0?
