Lunati vs. Hughes
Haven't run a Hughes cam but I am running a Lunati 60404 (.513/.533) right now and love it. Nice rumble and the torque is unbelievable for a cam of this size. Pulls strong well past 6000.
Here's a past thread concerning the Lunati cams. If you click on the link in the first post you can read from the designer of them.
