Wasnt there only one kind of allison engine i.e. the inline engine, or are
you talking about the one in the C130 hercules?!

Allison was the name of an engine manufacturer that made a
wide range of engines. IRC its now a subsidiary of RollsRoyce

There is an Allison transmission division of GM that still makes
[very good I understand] truck transmissions.

Is this a different Allison than the WWII engine maker?

Nope, they are the same people, the Allison Division of
G.M./Rolls-Royce.

Allison also Diesel engines for use in tractor-trailers & other such
applications. You can easily pick 'em out by ear, they've got a
distinctive high-frequency scream in their engine note.
