All Ms were rated for around 33HP at the drawbar.

The later Ms may have had more horsepower, but they were not "supposed" to. Any power was almost certainly gained through tighter tolerances in the cylinders as the years went on, which allowed the engine to produce higher compression.

On an engine the size of an M's, producing so little horsepower to begin with, it was very easy to get more horsepower.

When they went to the Super M, they made the cylinders bigger. That's how they got more power there.

The 400 has the same engine as a Super M.
The 450's cylinders are even bigger than a Super Ms, and it has the most horsepower of all.
