Default Detroit 353 diesel -- aluminum block? How to tell?

Correct

wether they are calling a
turbo a "blower" or not, or calling the supercharger a "blower". It
can be sort of confusing, or to me it is.


The primary difference between a turbo and a supercharger is the way
the blower is driven. A turbo by exhaust gases, and a supercharger by
gears, belts, or chains.
IIRC, the Detroit blower isn't driven by the exhaust, so I guess
technically, it wouldn't be a turbocharger. Supercharger maybe, but
for some reason Detroit just uses the term "blower" all through its
literature.

My uncle used to have an old Gallion road grader with a 4-71, and
interesting to note, it had a tube made into the casting that in cold
weather to aid starting, you would put these "ether" pellets in the
tube and they would drop down onto the blowers vanes, and when
cranking the vanes would crush the pellets and sent the particles
spraying into the cylinders.I thought that was kind of crude, but but
it worked, but hey! the whole line of engines were kind of crude too!
