I have 80 ft-lbs of torque @ 420 ft/min (Tw)
what is the power?
is ft/min a correct unit for angular velocity?
I came up with P=33600 but don't know what units to assign

As stated, there is insufficient information to solve. The proper units of angular velocity are radians per second. (There are 2*pi radians in 1 revolution).
What is the physical interpretation of the 420 ft/min? Is it the surface speed of a wheel, or the speed of a belt on a pulley? If you know the radius, you could determine the angular velocity.
Note that 420 ft/min is 7 ft/sec. If this linear velocity is the also the surface velocity of some wheel or pulley, then divide by the radius (in ft) to get angular velocity in rad/s.
