    OBS TO 6.0 4X4 Help!!!

    Guys ive been trying to find this info on here but ive been at it for hours!I have a 2000 Yukon Denali OBS 5.7Vortec and want to swap to ls, ive found 2 candidates 5.3 & 6.0 both are around 00-01 complete with auto trans and transfer case i have found the mounts,gonna get NP to take care of the wiring,dont know about the a/c bracket yet,but my main concern is can i put in the complete setup from the donor truck and keep my driveshafts?Or would it be easier to just swap the motor?And are they anything else i need to watch out for?Guys any help would be greatful!!

    So would it be easier to just swap the motor? Is that gonna move the trans. any?

    i did a 6.0 swap last year into a 98 4x4 suburban.
    i had to use the 1 inch forward adaptor plates so i would not have to mess with the driveshaft lengths.
    i had to go aftermarket for the compressor and a/c bracket because the compressor will not do in the orig location due to frame and control arm mounts. i will look for the name of the company i used for the bracket(i found them on ebay).
