From a tuning perspective, running the LS1 PCM is a far better option. The older PCM is so much more adjustable and has the "nice features" that aren't available on the newer models.

I think it's six of one, half a dozen of the other.

The LS1 PCM and wiring is much cheaper than the newer stuff and to conect to an L76 is very easy, (just a few loom extensions), BUT you do have to change the reluctor wheel.

The newer wiring is a bit more of a hassle because you need part of the body loom to get the thing running which then has to be modified by someone, (which again adds more expense), BUT you don't have to modify the engine.

If it was me (and I will probably do it down the track too), I would fit the L76 with the older PCM and wiring.

The drag racer in me says: "if you have to take the crank out you might as well put a big arm in there and get 402 cubes".....
