5,7 Cam Timing

Slowly putting together a 2012 5.7 Ram engine with a 392 cam to replace the old 340 in my Duster. I am planning to lock up the cam phaser with the Comp Cams part. I was wondering if there is a way to still adjust cam timing I don't know if the lock out sets the cam straight up since these cams were made to advance and retard especially after determining cam center line. I was wondering if anyone experienced any issues with a similar setup
You are putting the cart before the horse IMO. Why lock the vvt out for certain if you arent sure what ecu and harness you will be using? 2012 and newer can even use the mopar kit, no?
Unless you are planning on a cam swap? Even at that, the mopar ecu is unlocked for tuning.

Food for thought.
