I'm an electronics guy and amateur radio operator originally licensed as a kid of 12 back in . . . well, a long time ago.
Some of the interference to AM radio comes in through the 12 VDC power line and for that, a power line filter may well help. But most of the interference comes right in from the antenna and for that, the only hope is to "kill" the interference at the source.
Capacitors for electric motors (heater, generator, fans, windshield wipers, etc.) and
Either resistance wiring to the spark plugs or else individual resistor suppressors on the plugs
In the end, there is no guaranty that these attempts to cure interference will work very well. Park under a power line or sit near a fluorescent light and the noise will come in.
It's probably reasonable to look at the installation of an AM radio as a visual "prop" or a nostalgic feeling stimulating device or aid.
If one really must have music and news in a Healey, an FM radio with a good amplifier and maybe bluetooth input would be a good way to go.
Ray's installation looks especially good, assuming one is not overly concerned with sticking to pre 1970 technology.
