You are welcome, sounds like you are headed down the right track.
M1 used to "recommend" m1 for ms6395 which is your hemi spec. This is what some oil companies do when they don't want to cert an oil for whatever reason, in this case a very good reason, FCA gave a sweetheart deal to Pennzoil and m1 was upset about it. A couple years ago, m1 took the recommendation down. I believe this is m1's way of letting FCA know that they are bigger then FCA and they are running the show and m1 not having the spec is a poor reflection on FCA not m1. FCA acted very inappropriately giving Pennzoil a chance to meet a 2 year spec before even releasing the testing for the spec to other companies. A big nono unless you like monopolies. I hope you have a costco, m1 best deal for a top shelf oil on the planet.
A side note, if you ever get hemi tick from lifters, research hemi tick and lubrication. Also, something to consider is doing a uoa when the truck is in the 40k mile on odo range, if already there maybe want to consider this, do a uoa and look for wear metals asc with the cam. If they are shown blackstone will let you know. If you do have these metals there are a couple moves you can make as a strategy to protect that Cam. At that point look at and research 5w30 and ester/pao super high moly formulas.
