I apologize for getting techy in my first post =o)
This is a common, and very false, misconception. It makes engineers in the automotive aftermarket cringe.

Horsepower equals torque multiplied by rpm, divided by a constant.
That's literally it. It's just different calculation based on twisting force.
It's all power, and higher HP with the same torque will still accelerate faster and pull better, even if the measured torque remains unchanged.

They both get you going and keep you going, we've just come to associate torque with acceleration, but it's a far over simplified and inaccurate misconception.

At any rate, I've rented a Monterey 22FS 3 years in a row with the 4.5 250 and the thing rips 50+ with no issues and it tows well.
I just bought an M22 with the same engine. It's a good one and it makes a good argument against the 6.2..which is more thirsty and doesn't make a whole lot more power.
