```
Horsepower = (Displacement in cubic inches) x (RPM) x (Torque in lb-ft) / 5252
```
Since 414 cc is approximately 25.26 cubic inches, let's calculate the horsepower (hp) assuming an engine speed (RPM) of 6000 and a torque of 30 lb-ft:
```
Horsepower = (25.26 cubic inches) x (6000 RPM) x (30 lb-ft) / 5252 = 27.69 hp
```
Therefore, a 414 cc engine with an RPM of 6000 and a torque of 30 lb-ft has approximately 27.69 horsepower. Keep in mind that these values are approximate and can vary based on various factors such as engine design, efficiency, and specific operating conditions.
