Yes. But with a big cam you might want more stall speed. You will find out when you put it in gear. If you have to stand on the brake more than just slightly to stop the car pulling away at idle then you need more stall speed.

How Much?

The industry standard for the proper stall for a torque converter is 500 rpm above where the camshaft starts making power.
Example: The power band of your camshaft say is 2000 to 6000 rpm for sake of arguement, then the converter to use would be one with a stall speed of around 2500 rpm.
I've previously posted on this subject before, and if I can be of any help to you, I'll be pleased to do so.
If you are going to contact me, please pass the following information on to me.
Engine size, cam shaft specifications, rear axle ratio, tire size, horse power and torque curve only if you've got a dyno sheet from a real dyno, not one off your personal computer. PC dyno reports are terribly inaccurate.
