1966 Dart D-Dart cam spec

I appreciate everyone's input, I am just trying to find a cam that will perform and have some kind of sound profile, I don't plan on driving the car much outside of town, it is just a street machine and if I want to go fast, I have other cars that will serve that purpose. I just want my Dart to sound good and perform better than it does. That little E-2 I have is just terrible, sounds like a sewing machine and I just can't live with that. If anyone has a good recommendation on what cam to get, I would appreciate or otherwise I am gonna buy this cam: SB Chrysler Performance Flat Tappet Cam & Lifter Kit - 286°/294°, 242°/246°@ | USA Performance Parts

Have Isky grind that custom one, or have my buddy Don Johansen grind me a true D-Dart cam.

On the rear end gears, I know a 3.91 is gonna be steep with the 3.09 first gear in the 4 speed, but they were affordable and are for the 741 case in my early B-Body rear end in my Dart.
