Scooby, I know you’re a lifelong truck driver so I try to keep that in mind, but what on earth does a story about a 67 Pete and a bunch of cab lizard lingo have to do with the OPs topic? Besides hearing yourself reminiscing about the past?
I'll start by saying not sure what "cab lizard lingo" you are offended by. (or even what a cab lizard is) Would most readers know any more if I called it 12V71 Detroit Diesel? I think I used a description of a 12 cylinder 2 stroke engine. But the reason I mentioned it was to point out how long the technology for exhaust brake was around, but not commonly used. Somebody else pointed out the early pickup sized diesels did not come equipped.
While the exhaust brake idea was available for larger heavier duty engines long before pickups got diesels, most buyers that wanted to use engine braking (very small percentage) would spec the more expensive, and more effective, system that changed valve action to use compression in the cyl, but let exhaust flow once past the valves.
