I was thumbing through a catalog from Speedway Motors. *They advertise

engine worthy of aircraft use, by simply 1) ordering an aftermarket
engine with fuel injection, such as the chevy "RamJet" crate engine,
2) adding a dry sump lubrication system to it (not too strange
addition to high perf cars nowadays), and 3)-adding the magneto from
Speedway. *Use direct drive to keep the RPM low and reliability high.
I doubt that today's hi perf crate engines lack the torque to turn a
prop at 1:1.

If this is unsafe, specifically why?

I know someone could fly within 100 miles of a t-storm and have the
static electricity play with the ignition system, but stop a magneto?
If you were struck with lightning, your auto-engine might stop, but
then your resin might burn and melt, leaving you with some loose
fiberglass to negotiate a crash. *Point I'm making is, experimental
planes near t-storms have bigger probs to worry about, don't they?

BTW, that magneto appears to be offered just for big and small block
chevy's. *Aside from that, the models they carry are "nostalgia
engines"...1950 hemis, flat head fords and the like. *Another caveat:
they cost $1100...but even with that and a $1200 dry sump system, we
are still way under the cost of an O-540.

How about this one:
