Just to add a little more to Neil's comment...
Yes, MMI
used to sell the 3Ω Flamethower on their site.
(In fact, I also bought one)
This was before Neil did some research (a lot actually) and discovered that their claim (PERTRONIX not MMI) of a perfect match to their EI unit was, in fact, bogus.
If I understand correctly, once we'd made the discovery of needing additional resistance to avoid overheating (sorry, you'll have to actually READ the thread)
that was when MMI stopped offering the Flamethrower coils.
The coil now offered is at the necessary 4Ω requirement.
As I said, give Ken a call and he'll make sure you're set up proper if you have any doubt.
Just wanted to clear up any confusion to Bob regarding the Flamethrower originally offered on the site.
