Which cam will work decently with stock magnum tune?

I agree. There is alot of power hidden in those magnum 5.2 and 5.9 motors. I wish he would test it with a 52mm throttle body!

380hp crate motor was dynoed with a 650cfm carb from the factory and listed as 380hp. Put a 750 or 780 carb on them and they gain over 20hp. All the factory dyno results I seen stated they tested with a 650 carb. They guy in on the development also said they used a 650 for testing
