The HEI does have some solid advantages over the Mopar box, but I'm super-suspicious of MSD coils any more, since they're now outsourced to China. :roll:
I'd probably use a spool-type stock HEI coil.

Installed an HEI ignition module with relays over the weekend. Makes a TREEEEEmendous difference. Still using the MSD blaster coil. When I get some more time and money will go with a GM-type.

Running much much better. And thanks to Dan's excellent directions, it was a very simple swap.

Thanks everybody!!

madmax, he's not running platinum plugs. He is, however, running Autolite plugs, which are now rather poorly made in China.

A switch to NGK ZFR5N plugs, without the metal ring washers, might be a wise idea to eliminate poorly-made plugs as a cause.

I don't have much knowledge of propane engine operation but I have a hard time imagining why an extra-narrow plug gap like 0.030" would be anything but a hindrance.

What kind of Mopar electronic ignition are we talking about? Orange box...?
I second using NGK's. When I ran them in a waverunner I loved them compared to Champion's or others.
