I have a 1979 f100 with a 460 with a 3500 stall converter and the transmission shifts too soon .How can I get it to shift around 3500 rpm? Thanks for the help

You can try turning the screw inside the modulator in a few turns.

There are different modulator pin lengths that will help.

Some trucks had a very early shift pattern, the large governor weight has a big honking slug inside of it that is one cause for the quick shifting.

Did you happen to change gears recently , the Gov responds to drive shaft speed not just RPM's , the Gov weight can be modified ,but not easy job
