Cam change question

[56taskforce]

Has Anyone tried a cam swap without head removal?
Just wondering if the lifters will move out of the way enough if you roll the engine upside down on the sand to change the cam without removing the heads????

It can be done. You'll have to pull the valve covers and all the stuff in the way to gain access the the lifters. Upside down might work or you can do something like this guy did with magnets

Cam Swap in truck!

So I saw a thread a little while back about a guy asking if a cam can be swapped in the truck on a duramax. So here is what I was up to Saturday! The answer to the question is yes, it can be done and its really not all that bad to do! Was about 3 hours in and had the stock cam out already...

I’m sure it can be, not far off of how you pull the cam on a cummins with hydraulic lifters
