While that would work with the stock magnum computer, I don't think it will work here. But again it comes down to what is the output of that distributer vs the other choices.

The other main draw back was the whole transmission thing to me for using the stock crank sensor.

IF you kept the 518, then it isn't a problem. But if you went with a different trans Like I did, keeping the 727, then it becomes a bit different I think.

The b&m flex plate replaces the stock magnum one for the neutral balanced torque converter. I was never clear on this, but my guess would be having to replace the torque converter to allow use of the stock flex plate at that point.

This just seemed to be a cleaner way, and allow you to use any of the magnums instead of the 95 and earlier for the simple ecu. or making your own from mega squirt.
