LS1 swap guys, help me out!!

[Tfish]

I know there are a few guys doing the LSX swap into these trucks and wanted to get some advice from ya before I pull the trigger on and engine/trans setup. I would ultimately like to do and ls1 swap possible an ls2-3 down the road for the selectable 8-4 cylinder while cruising.

Right now I could probably track down an LS1 with tranny wire harness ecu... but I'm tempted to look at the "LQ" engines since they are the same just cast instead of aluminum... and are a LOT cheaper and easy to find!

Anything I should look for specifically or transmission preference? I have heard the 4l60e's are kinda weak and a better option might be the 4l80e... Let me know what you guys think!!
