Right, the LT5 was a fresh design. I suppose the point I was getting at was the crank reluctor wheel is inthe middle of the crank, like I had thought. This design was used on many other GM vehicles during that era. While the lt5 ignition system wasn't used on any other GM v8, it was a similar design to what they had existing in other DIS systems. I knew lotus designed the engine, merc manufactured the engines, but I have a good feeling GM had a hand in the ignition, fuel and ECM. But I am in no way an expert on the LT5, I know very little about this amazing machine.

On the GM designs that were similar, they had a reluctor cast into the crank, and the grooves were machined. The v6s used 7 notches, similar to how the LT5 used 9, one for the reset. The used an ICM that controlled much if not all of the spark control using the signal that was returned from the ECM. I would Almsot bet they have the same connectors on the LT5 ICM with the same in and outs that the other GM DIS systems had.

Not to dispute the information you have provided, but this design is extremely similar to other GM designs of the time.

Regardless, the information I was providing is that GM made a 24x reluctor wheel, than can be heated an pressed over the existing crank on an older 60* V6. If, by chance, the cast reluctor inside of the LT5 is about 5.75 inches, this reluctor that was used on the V6 could be used on the LT5 for 24x conversion. I have one of these reluctor wheels that I am working with, and just thought I'd share that with you guys, just in case someone wants to give it some more research.
