I''m not sure about those distributors, but
they don't appear to be normal marine
hemi units. From the pics you posted, I
noticed that the plug wires appear to be
metal-shielded type, with threaded
metal-shielded connectors at the distributor
cap and at the valve-cover spark plug tubes.
Ignition shielding like that is used to prevent
radio interference where VHF or UHF two-way
communication radios are used and is usually
only seen on aircraft engines and on military
applications. I wonder if those engines were
originally ordered by the military, maybe the
navy or coast guard? I've never seen a set-up
like that on a normal "civilian" Chrysler marine
engine. Do the distributor caps have a metal
casing or covering on them too?
