    350 Vortec to LS1 swap

    Ok so I am in need of a new engine for my 01 Express Van and cant find a 350 vortec for a reasonable price how ever I can find the 5.3l LS engines all day long complete with wiring for super cheap. So my question is, how hard is it to swap a LS1 into a truck that had a Vortec 350 in it? I dont have a problem doing the research to find the stuff to do it but thought I would ask first if it is a easy swap or not. Any info would help me make my decision if I want to go this route or not.......Thanks Mike.
