    Cam only, stock springs possible in 6.4 VVT non MDS?

    I have a 2012 6.4 SRT chally crate motor, non MDS for manual transmission in my 2013 Daytona automatic. I have long tubes, 3200 stall, and 3.73 Getrag. Just miss that lumpy idle from a cam, but not wanting to get into needing heads etc. and emissions risk. Any known good performance cams that are compatible with the stock springs pushrod and timing parts? Can I swap springs in the car if needed? Not looking for an engine building thread, just do these engines have a mild cam selection that won't hurt or just not be worth the labor at all. Thanks
    Modern Muscle NSR-STG3-LP says no springs required,??

    I looked forever and have come to the conclusion that doing a cam in a 392 is pretty much a full tear down and rebuild outside of the short block. They all say they need springs and VVT limiter.
