actually it is pretty easy....as far as swaps go.....it depends on whats available to you, you may be able to find complete LS1's or LS2"s ect. or complete vehicles...I had to search for awhile before I found my 6.0/4l80e out of a wrecked van...I think the truck motors are beter suited if you plan on rebuilding, or boostin it...there is also more and more aftermarket parts available everyday...in the meantime you can check out LS1Tech..some great info over there....
