whats the horsepower torque etc on the 88-91 chevy 454 engines. Right now my mom has a chevy 1990 chevy c/k 3500 non dually withe the 350 engine in it and she wants more power because she pulls a horse trailer. Does the 454 engine have enough power to pull heavy loads with ease? She needs plenty of power because we are going to get a goosneck horse trailer and diesel is out of the option. Does anybody have any idea how much a chevy c/k 3500 (88-90) dually with 454 engine can aproximately fifth wheel pull?

will i know the 454SS which i think has the same eng makes 255hp and 405torque but i'm not sure how much in can pull but i think it would be around 10,000lbs

are u selling that 350 i might be interested (454 is enough)
