Engine Swap information
 

Hey guys,
Fairly new here, but hoping to get some good advice.

I picked up an 01 Tahoe LS about 8 months ago, awesome shape and I love it.
5.3, 4x4, really happy with it.

given this is my second vehicle and I want to make a "toy" out of it, ive been looking into an engine swap.

some random websites said the LS6 (01-04 Z06) will bolt right in ? is this true ?
Im looking for a simple swap, I dont want to get into shifting mounts around and cutting and hacking the truck apart.
Seems the LQ9 is also another option ? is this a bolt in ? given I get complete engine and harness and ECU ?

Any advice on what I can do and whats possible would be great (yes anything in possible wiht $$$), but Im looking for something without running into massive modifications or troubles.

Thanks
