Picking up a 2014 5.7 in a few days...

Go over to moparts. There has been recent discussion on this very subject.

Just read the thread about it, seems a few guys did it successfully with their trucks... if it works that well in a heavy truck it should be lots of fun in a 3300-lb A-body, and I'll be getting it tuned as well. I'm also looking at intake manifold options, it came with the dual-runner truck intake which is not only huge but this one has a busted flapper-actuator module. Something that's an upgrade not just a regular car 5.7 intake, like a 6.1 piece (?)
