hey guys, i have a complete 5.3L except for the wire harness (ive never worked on a EFI BEFORE) but i am planning on slapping on a turbo w/ LS6 cam & valve train. but i dont know if this engine even runs. ive seen on youtube ppl starting up LS motors on a stand. i was wondering what i would need & how i would be able to make this happen? & another thing, i was thinking of buying the mega squirt II, has anyone use this & how do u like it? thanx for any help
