TTI headers installed, pictures anybody?

Hydraulic cam. I've been told to run the motor at 2500 RPM for 30 minutes to break in the cam.

All (stock'ish) 3rd gen Hemi-cams are hydraulic, afaik.
I'm not aware you can get flattappet cams for 3rd gen Hemi's, but if so, then yes break them in as stated.

With a rollercam, either hydraulic or solid, you don't have to break in the cam.
