I'm purchasing a 94 gmc sierra z71 4x4 that needs a motor and was looking to see if its worth doing an LS SWAP. The truck will more than likely be my hunting rig and possibly be a daily driver to keep miles off of my 2012 SVT raptor. So I guess what I'm trying to find out is what all is needed if I'm going to use the factory transmission and what its going to cost to complete the swap after the engine purchase. What all extra am I going to have to build/buy? I would like everything to work as it normally would. Any help is appreciated! Thanks for your time! EDIT- the green truck is accounted for also.
