All Cammed up
A cam is not going to change your cruise rpm. If you were seeing 2,500 rpm with 3.55s and a 30.5" tire, your torque converter wasn't locked up.
No it doesn't rid the cam phaser noise. I have heard before switching to a synthetic oil supposedly helps the noise I just bought Amsoil oil and filter so I'll let you know if the oil switch helps with the phased noise.
