Just another cam pick question.

I have been thinking about swapping out the cam in my small block recently.

The motor is a 360 bored .30 over
Speed pro flat tops
Eddie aluminum heads
Eddie performer rpm intake
Holley 750 dp

Currently I have the older mopar .484 lift purple cam in the car. I love the sound and I am fairly happy with the performance of the car but I have been wondering if this is the weak point of my motor. If it is what would be a better cam for my motor. It goes to the track 5-10 times a year and I am running 3:55 gears at the moment but plan on going up closer to 4:11.
