Anywhere from 350 to over 600, and that doesn't include what can be achieved with modifications.
250 - 600+. Really depends on what the engine is and what rating it was purchased at.
The Volvo D16 engine outside of the North American market is available with up to 750 horsepower.
Depends on torque and gearing. A 12 or 13 liter diesel engine kicking out 340 horsepower isn't going to be the same as a 5 or 6 liter gas engine doing the same. There's much more to this equation than just horsepower.
if the engine is stock it has 160 horsepower
It is a 150 horse power horizontal engine
Advertised Horsepower is : 155 HP @ 4000 RPMs.
It is a 410 horsepower engine but ford rated it at 315 hp for insurance reasons!

You need to specify which model Caterpillar motor you have. 455 is just a horsepower rating - several models were available with a 455 horsepower rating, to include the 3406B, 3406E, C12, C13, and C15.
advertised horsepower is...........165HP @ 3800 RPMs.
The rated horsepower of a 1999 K2500 Chevy truck is 255. The base engine is a V-8 that is 5.7 cubic liters.
Obviously, this is different with every truck, as there are many different sizes and makers of the engines that are used in semi trucks. The lower end of the scale, used in small or older semi trucks and straight trucks, would be around 275-300 horsepower. The upper end of the scale, as in large new over-the-road semi trucks, would be around 500-600 horsepower maximum. The average semi truck you see every day on the road or around town would probably be right around 400-450 horsepower.
