Good points, Jerry. In my application, the Holley helped the 4000 series truck cruise at 65 MPH at 3,000 RPM (weight was right around 12,000 lbs.) However, the engine would *not* hold 65 on much of a hill. Load the water tank (Truck's max GVW) and the truck went to about 19,500 to 20,000 lbs (depending on what I had for lunch). At that point, 65 became more of a challenge.
I would think in a little truck, the Holley would help him cruise a lot better while keeping the RPMs manageable?
