got these answers off the jakebrake website, i know you probably have the 6.0 and not the 7.3 but the answer is the same.
FAQ4:
Do you make a product for the Ford 7.3L Powerstroke or Navistar International T444E engines?
ANSWER:
No, Jacobs does not offer an exhaust or engine brake for these engines in fact, Navistar and Ford have requested that we do not develop one for these engines.
The primary concern with putting a retarder on these engines is their use of hydraulic lifters. Most engines with hydraulic lifters have fairly low exhaust back pressure limits so the performance of an exhaust brake would not be substantial. More importantly the use of an exhaust brake on an engine with hydraulic lifters can cause engine damage. The problem is that the increased back pressure resulting from the operation of the exhaust brake will cause some degree of valve float. This valve float can cause the hydraulic lifter to re-set with the valve still open (not seated). This phenomenon is known as lifter jacking. Lifter jacking could also result if a traditional engine brake were used on these engines. The results of lifter jacking can be anything from low positive power (because the valves stay open) to engine damage caused by valve to piston contact.

Dodge offers a "Jake" brake which it is not it is actually a new version of the old Williams Exhaust Brake.This is really just a butterfly valve in the exhaust pipe to put back pressure on the engine. A true Jake brake operates in the valve train to actually turn the engine into a compressor to help hold the vehicle back.

I don't think you can for a pick-up size engine and truck. Jake brakes are for semi-truck tractors and aid in slowing them down. They are not legal to use in most towns/cities because of the noise and they wouldn't be practical to use, either. It's more complicated than just putting one on.
Matt has the right answer and should get 'best answer'. Good job Matt.
