Pretty crappy of the people you got this "rebuilt" engine from to not stand by their work with as few miles on it, if this is the same engine in your other thread:
First post here. So.. 2012 2500 hemi. when I first start the engine sounds great no lifter tick. After about 5 miles or so ( the oil temp is over 110 degrees at this point my lifters sound very bad, loud ticking and some power loss. Then after another 5 miles or so the noise all but goes away...

I repaired my MDS hemi <6 months ago, using mostly OE parts, even replacing a couple things I didn't have to, dropped close to $6k
That was almost everything except pistons, rings, injectors, and the cam, crank, and rod bearings.
Be prepared to spend $$$$ if you want stronger than stock, might be better off buying a crate engine instead.
Please post where you got the "rebuilt" engine from so others can avoid them.
Post some vids of your "tick" to YouTube and link them here. Maybe there is an easier solution to your issue, and until you know for sure whether it's a lifter or other problem, it's harder to figure the best solution.
