Governor? Do all 6.2L's have governors? I haven't hit it yet. If it does have one I'll feel much better about the RPM's I've seen. Perhaps too much damage hasn't occurred.
Yes, all 6.2L's have governors. You can't damage the engine by running down the highway too fast. The only way to damage the engine from high rpm is by trying to hold the truck back by means of engine braking when coming down a mountain, but that would be hard to do.
You can hit the governor in these engines, but it sounds like you're about to push the pistons out of the heads! But it doesn't hurt anything, it just sounds bad. Next time you drive the truck, just push the throttle all the way down when in third gear, and it'll rev up and all of a sudden stop accelerating and hold a steady high rpm. Then you can shift into 4th. It's a funny feeling.
When my engine was still n/a, I used to run up to the governor in each gear before shifting when towing large loads. Now with the turbo and other mods, it has enough torque that it likes to shift much sooner.
