2015 RT 5.7 M6
It's just logical that a 6.2 cam that is specifically made for a forced induction application is the way to go. If Luke had not mentioned a while ago that the swap was possible, I was going to go with a custom SC grind. The correct cam is 5038761AA and is $230 and no VVT lock-out required which makes for a very cost effective swap. Only problem is, I think I have had the hood open longer than I actually have driven the car. Can't help it...I love to wrench...beats lying on a couch talking to a shrink about my childhood. :grin2:Why a 6.2 and not a 6.4 cam?
The 6.4 cam was cheap when initially introduced but now is around $350.
I didn't need to drop the oil pan when I did the swap on the 5.7, just remove the 4 bolts on the front to remove the timing cover.
You'll need 3 feeler gauges to setup the oil pump correctly.
If you do a search I did a fairly comprehensive write-up on the install I did a few years ago.
edit: and all the gaskets are re-usable rubber/silicone.

Also according to HRN:
"Because the supercharger is forcing air into the engine, aggressive cam profiles, cylinder head porting, or high compression ratios aren’t necessary to achieve big power levels. In fact, supercharged engines respond to camshafts with wider lobe separation angles, which are conducive to smooth idle and big midrange torque as well. "
