The engine doesn't necessarily roll around the crankshaft. It has a roll
center, just like the suspension does.
But, looking from the front towards the rear (opposite the normal direction,
for clarity I hope), the crankshaft rotates clockwise meaning torque
reaction should move the engine block counterclockwise. I believe that
would cause the tip of the arm to move mostly downward and to the right,
where it will hit the frame.
BTW when I mentioned my air filters hitting the inner fender, I neglected to
mention that I use TR4A paper element filters on my TR3/A engine. The metal
TR3/A filters mount higher on the carbs, and almost certainly would not hit.
They also won't stop anything smaller than a boulder, and since I live
between the beach and the desert, I feel like I need a little bit better
filtration than the factory supplied.
