Some Gen III Hemi questions.

I have done this very thing. 2011 5.7. Removed crank and installed early tone ring. Installed a 6.4 cam. Used the prefix CASCAR intake. I did not lock out the phaser. I can't be positive, but, I think the timing may have been "moving around".
It did not seem to have the same oomph as the previous early 5.7 with Eagle heads and 6.1 cam. I would look at a cam that actually requires to be locked to use with the carb. The 6.4 cam with injection and VVT function is an animal.
