Dyno costs

Hey, I've been eager to get my 460 up onto a dyno for a while now, but I really don't know where to start. What's a good way to find out where I can even do it? The yellow pages? heh, also, what are the costs involved? Typically how much is it for an hour on the dyno, etc.

Check this site. They should have a listing of dynos in your area.
