Yeah, no technical problem. But the Megasquirt box just needs a very plain on-off 12V signal from the distributor - and it certainly doesn't need the heavy duty switching capability of the Crane box. Using a pertronix would at least eliminate one box under the hood. The output from the megasquirt box (adjusted for advance based on MAP and RPM) is a light-weight 12V signal that certainly can't handle the coil directly. Now that megasquirt can handle the dwell as well the using an MSD box might be a little more capability than needed, but you can always turn dwell control off in megasquirt.

The EDIS would just look cool. I'd just need to attach the 36:1-tooth wheel to the front pulley, rig a bracket for the sensor, and do a little wiring. No distributor at all - just a little 4-HT wire coil pack. I don't know that it would work any better, but the idea of reducing the part count under the hood is appealing.

5700+ rpm is about where the PV's engine used to get a bit weak and wavery with the stock ignition. I could have sworn it was carburettor or valvetrain related. But it went away when I put on the Crane and a big old Mallory Voltmaster. That change and that change alone allowed it to pull cleanly and crisply right up to 7000 rpm (butt dynanometer) - about as high as I used to rev it. (Of course, after about a year of occasional 7K bursts I spun that rod bearing!) I don't know if the points themselves were bouncing and affecting the timing, or bouncing and affecting the dwell, or even just the faster firing negatively impacting the dwell somehow. It never would actually miss, but instead you could just feel a sort of wavering weakness and torque drop off.
