HELP me out Mopar Fans !!! (CAM question here)

original: 273 had a 2bl carb

Converted to Mopar Dual plane intake with a 4bbl witha Edelbrock 4150 600 CFM carb, Stock heads, stock pistons, just want to add a some thump to the motor. has a mechanical cam!

Which CAM would be good for this motor (<--273) to add some sound to as well as little more power. Ive been waiting on headers under chassis long tubes, also want to add a vicious fan kit, any info would be appreciated lots and lots!!!
