The Trick Flow cams available for that engine seem to be:
duration @.050
221-225
224-232
236-248
I am guessing it must be the 224-232, 2500-6000 rpms. If that is the cam then the limiting factor would be the heads as Brent said. I am thinking that engine could put out about 330 hp, give or take 20 hp. If this is for a street car that would not be a bad engine. In fact if it was mine I would have preferred the 221-225 cam with those heads for street use, but we don't know what rear axle gears are in the car.
