The 413 (sometimes called the semi hemi) is/was an industrial engine
Used to power irrigation systems, hydraulics etc..

My first motorhome a 1972 lifetime by Boise cascade
Had the 413

And gas mileage sucked

There were two 413s. The P (premium) engine was for trucks/RVs, with high mount water pump, different heads and manifolds.
The standard 413 was a "high B block", used in cars, and parts from the 440 would interchange.
