Carb or EFI?
What type of exhaust?
Roller or Flat tappet?
I am going to use a Merc/Crane 500EFI cam in the 9:1 454 I am building...

The Comp Cams cam you have listed probably has steeper ramps but is not that much bigger than what is in your engine now. I don't think you will see a significant power increase vs. the ZZ502 cam. It may have a better idle with the 112LSA though.
