How does the corresponding cam lobe look? Any photos of it?
Strange finds in valve cover and glow plug hole

Pretty grooved now that I can see it from the other hole. I have the camshaft from the 6.9 but i havent looked at it yet and I have to be out of this garage asap. :/

Do i have to pull the motor or can I swap the camshafts in the truck if I pull the condenser, radiator, etc

Are you gonna upgrade to a typ4 cam?

On the plus side, it's a good candidate for a Typ4 cam core now.
I think that you can pull the cam by just removing the radiator. I think the condensor can stay, but don't quote me on that.
I've always been curious how regrinding a cam works, like you're taking material off, right? How do you make the cam profile taller?
As for the condenser, should be able to flip it out of the way without disconnecting it.

If the lift is increased my guess would be that material is removed from the opposite side of the lobe to allow the lifter to drop a bit lower, so from the bottom the lift would be grater.

No, guys, the lobes are welded to build them up higher/bigger then they are reground down to the new desired size/shape.
I did exactly that when I swapped my engine

Sounds like I can definitely just do this in the truck and the time is now while the valley is still open and theres no coolant anywhere.
If this other camshaft is good and I go about swapping it in, what other things should I be on the lookout for while Im in there? I have the manual and will study it before moving forward for take down and reassembly, but do yall have thoughts or tips? Special tools I should have or need to improvise? Should I assume the camshaft bushings are trashed too?

Man I would, but right now I have a used one that I hope is okay. I might in the future, though, especially if this grooved one really is good for a core. I didnt even think about it til yall brought it up.
@IDIBRONCO thanks for the clarification. I had assumed that is what was done, I also assume they do some sort of heat treatment to them to re-harden the surface on them.

All of the re ground cams i have seen, and i am speaking of flat tappet cams, they did remove material from the base circle of the cam. All were stock style cams though. Even had one that was ground with really low lift, during the time lifters were junk and would wipe out cam lobes..
