Best cam for gen 3 daily driver 6.1 in 72 Demon

You are confirming my original thoughts! I have already put 355s in. I just don't see a lot of benefit to the expenditure if I don't do the heads? I mean for a daily driver I think it will rock! It was just that the motor is staring at me out of the car, cam swap becomes super easy! But holy smokes stock HP is nuts to begin with.
I had long discussions with the guys at HHP about what to do to get a nice bit of performance boost out of the 6.1 in my 2006 Charger SRT but still keep it able to use daily on the street comfortably. In the end, I put in a 3.92 Getrag LSD and it is awesome! Pulls the power band in nice and tight and provides nearly instant acceleration. I also added a 93 octane tune from DiabloSport to optimize A/F across the full RPM range.
