Hey all I am looking for insight on deleting the dfm system on my 2019 

I have the 5.3 L84 engine. 

I have the engine apart already and all parts on order.

As much research as I did I am now getting conflicting info about the Camshaft.

Per the website and what I researched the cam needed to be swapped out to non dod cam.

I ordered that one but now I am getting info that the cam possibly does not need to be swapped on this particular engine even when replacing all the lifters to non dfm style.

Can anyone confirm either way??

So what did you ever end up finding out about the camshaft? I emailed Michigan Motorsports and they replied saying that a new oil pump is not needed and a new camshaft is not needed either as long as it's not damaged from failure (mine isn't). I just wanted to confirm that this is correct info for when I decide to do my delete. It just seems odd that you wouldn't need a new one.
