NFry said:I am thinking about a cam , for fuel mileage. I tow some (12000 to 15000 lbs) some times. Is there anyone that has changed there cam that could tell me if it did help there mileage & how much , and what cam you got. I am getting around 650 to 700 miles on a tank(solo) Thanks
Rams-n-Hogs said:To be honest, if your getting 650 to 700 miles out of a tank, I'm not sure the cam is worth the expense, and labor, involved. With my setup, it did absolutely nothing for my mileage. I'm not saying it won't help on your truck, but it would probably take at least a couple of years to recoup the expense. I have the Helix 2.
