What cam should I get?

Price. That's why I didn't get it! lol.
I always thought that the vacuum advanced helped keep the timing more stable as you go up in rpm. If I remember correctly I didn't have it hooked up on the Charger.???
The way it sounds far as the above oil changes on this thread it sounds like the break-in stuff should be removed imediately or you will suffer engine damage. I mean that's the way they made it sound.lol. I don't know about it I never add anything to my oil.
