    I am looking for a factory torque and HP curve for the 1994, 454 ci motor. I believe that the peak HP was 230, but I am interested in the peak torque and at what RPM that happens. I tow a 20' box and at 65 MPH, I am at about 2300 to 2400 RPM in OD. I know I am not supposed to pull in OD, but in 3rd, I would be running some big RPM numbers and mileage would suck even more than it does now.

    Does any one have these HP and TORQUE curves?

    Thanks in advance.....

    And i pull in OD all the time with my 350, just if its kind of gooing up hill i shift in 3 rd.

    I thought that it was 230 hp that was increased to 290 hp (?) in 1996. Again, I could be wrong. It sure pulls like a lot more than 230 HP with about 380 FT/LBS of torque.

    I had a Bronco with 215 hp and 315 ft/lbs of torque and it did not pull NEARLY as well as this truck.
