Welcome to the board first off htrman. I guess your some kind of HVAC guy? any way I did a 6.0 swap on my 68 LeMans convert way back like in 05 when the LS thing was young still and hardly anyone had done anything with them. I have done several yes they are a good source of power the factory has them so choked back it isn't even funny to talk about how much power can be unleashed by a PCM reflash and simple things like exhaust upgrades and a fresh air inlet.On top of that if you talk a cam change them you really start to make some power. But I digress, I haven't done any research into the 4X4 aspect of the swap and to why a lift would be needed but different pans and want not are available now that may change that. As to the price the car versions are still high but the truck motor is what you would want I would think in your 4X4 anyway and if your doing a swap buy a combo pack with the motor trans and pcm and wiring and all from one truck so it will all be matched and easier to deal with that way.
And to Nittis, I'm sorry your so far away from me because when I junk out the late model trucks and Tahoes and Suburbans that I buy for the extra sheet metal I do sometimes have left over LS drive trains that I sell to help out the guys or ladies in our hobby, like the complete 5.3 with trans wiring and pcm for around $1200 That includes all acc. even the fan and belts and hoses in most cases
