4500 stall ??

This is probably a stupid question,but here it goes. The cam I have in my motor is a 267/274 @ .50 570 solid. The cam calls for a 4500 stall. Do I have to run the stall it calls for or can I run around a 3500 stall. That seems like a lot of stall. Mostly strip, occasional street driving. Any help would be appreciated. Thanks, Brett.
