That's what gave me the idea. Reading on the MSD multispark with RPM limiter
and boost adjusted retard.

At least the new Hemi has twin plugs. All the serious 426 race engines
were twin plug but the street Hemis, joke they were, had a dummy plug
in the second tapped hole. Would have added build cost for the second
distributor. Adding twin plugs to other common Hemi head engines like
the Harley Davidson Shovelhead, the BMW motorcycle flat twin, or even
the Jaguar XK improves economy and cuts octane requirement of the fuel.
Now if it only had a distributor hole...Even as it is EAA people are
already talking about putting the New Hemi to more serious employment.
After all a three blade constant speed Hartzell is the most efficient
transmission we may buy...

The injectors are right on top of the ports so I don't think fuel mix would
get into the unused cyl. The piston would have to go through the compression
stroke with no relief, but for a cyl with good compression that should have
some return force.

You mean that six cyl with the supercharger thinking. :)
If I was going to get a new/used vehicle for fuel economy it would
be an import econobox or one of those hybrids.. problem is what you
save in fuel you loose in insurance/tag/etc.
I'm just puttering with an idea.. putter..putter..putter..

They are out there. Many old car shops have a pile of them. They are
common to industrial, ag, marine and aircraft applications and those
people kept them long after all cars went to alternators. When Spards
DDA in Reno, NV did their 53 series Detroit swaps in pickups as late as
the early 80s they were still putting generators in...
There are in fact more generator cores out there than there are people
who want generators. You just have to look where they are and not where
is convenient. Even if 99% of those ever made have been smelted for
scrap that leaves tens of thousands.
