I had the 6.4 SRT(MDS) cam in my 2014's stock 5.7 , no issues, stock springs , no tune just plug and played. Ran about the same off idle to 3k, from about 3k on Pulled like a banshee till 6k , never did get it tuned....should of but didn't. If you plan on going past 6k I would opt for the 6.4 springs.
Just my $02 worth.

Some of us are so open minded they only see their View
