Anybody use GM LS computer/ coil by plug set up on 5.9 magnum???

The magnum doesn't have a knock sensor that I am aware of. It is basically a vibration analyzer, so it could be mounted anywhere that isn't on a water jacket ( the water will reduce the vibration and render the sensor basically useless). Does your co-worker have the intake off the First body? If so find out how much he wants for it. My co-worker is looking for one. If you are planning on running a cold air intake, you could always mount the MAF in the piping.
