“no engine...8 peddlers inside”
Actually, it would be equipped with a 460 cubic inch V8. Used this engine in Continentals, heavy duty pickups/vans and single axle trucks up to about 20,000 lb GVW.
That would be FORD’s FE engine, replaced in the mid 70s by the 335 ( 351 ) Cleveland engine, and the 385 engine family.
Also used in my ‘64 Ford Galaxy. Man can it fly!.
