As someone who bought a used 6.1 Hemi, and had to buy a second one to replace the first one lol. I'd say it is nice if you can be at a slightly lower or similar price point as the Mopar crate offering with additional stuff needed for install.
Can make sense to compare your 408 with FI to this Gen 3 option if someone wants to go that modern motor route.
I would consider Blueprint as a option. Keeping in mind that value for what you are getting would be a major driver. Although personally I don't care to make additional power and like to just enjoy with cruising. So I'd really like someone to offer a a great price "new" Gen 3 Hemi engines that are cheaper than existing crates and not taking the risk of having to get a used engine from a junkyard/ebay/etc.
My unknowns have been the ease of complete "one stop" shop for everything you need to install like a really complete kit with everything you could need to install.
