97 F250 HD 460/e4od...
I found an RPM calculator online and was playing around. I found that with my stock 235/75/16 tires (29.9 in dia) and 4.10 rear, that when im pulling my camper with no O/D at 62-65mph im hovering around 3000rpm.
Now i had my bottom end redone at 87,000 miles and i thought it was because of coolant intrusion due to the head gaskets popping, i still think it was...but...
3000rpm is way to much for a 460 to sustain on the hwy isnt it? For hours on end?
I dont have a tach but the motor didnt seem over taxed. Do you think the calculator didnt take a lock up converter into account?
Input??
