too much money unless he has it. someone was selling a LS2 on tr not long ago and he wanted something like $3.5k for it, dont even think it had a harness to it. LT1s or a q45 motor would probably be cheaper, though nowhere near as light as a LSX
Ls1tech is the place to go man. You might also want to call trans am creations or gm express...
I saw an lt1 sitting at noels muffler shop. Looked complete but without tranny....
