As stated by Dodge on their website and a test of my own, on my 2007 Dodge Ram 5.7L V8 HEMI, it tops at about 390hp. So in good condition you will be pushing 390hp.
No
The stock 5.7 liter Hemi in a Ram Pickup is 348 Cu inches and 345 HP.
It was advertised at 355 horse power.
yes it should not be a problem since they are the same generation. i would consult the shop that is going to be doing the work beforehand about it though
