Afternoon guys/gals:
This might be confusing and all over to some when I’m explaining and hopefully yall get it. I’ve been researching the MDS Delete. Besides the wear of the lobe and lifters and replacing that. Main question….Is the camshaft really required for a non mds camshaft? Is the lobe that different? Disengaging running on all 8, engaged running half the cylinder is it mainly just the solenoids shutting off/on the oil pressure to the cylinders. In simpler terms, can we just install a regular stock camshaft within block off solenoids, lifters and tune?

If that stock camshaft is for a 6 speed Challenger yes,but not reconmended on a stock truck cam. The 6 speed manual transmission 5.7 and 6.4 Challengers are non-mds cams,but you'll want to probably have it tuned for the cam.The lobe ramp profiles are differant between the mds lobes and non-mds lobes,so putting non-mds lifters on the mds lobes doesn't really pan out on the stock truck cam.You have to pull the heads to replace the lifters,and if you're that far into it,you might as well replace the cam with one that's a non-mds cam if you want to delete mds.

this plus change your water pump and timing stuff while you’re in there assuming you’re around the 100k or greater mark.

So short answer is yes. Plus going from mds to non MDs requires a tune like you mentioned; why buy another mds cam and pay to tune for non MDs on a less than ideal cam profile? If anything buy a better cam than oem depending on what you’re trying to do.

This is a buy once cry once scenario.
