stepper power question(s)

If I have two identical steppers.
same voltage, same current,
200 steps and 400 steps,
does the 400 steps deliver more
power? seems like if you deliver
1 amp per step, then it would
deliver more amps per revolution.

Second question,
I have a NEMA 23 1.1 ohm stepper
bi-polar. it is from the early
90's and I can't find any info on it.
is there a ballpark way to figure out
the volts and amps ?
