I have a stepper motor that seems to have promise as a good motor but, I know very few of the specs.
Can you guys help me?

Here is what I know and how I know it:
Nema 23, 8 wire motor - visual
2.4 ohms/coil - I measured it
4.3 volts - Label
1.8 amps/phase - Label
120 oz/in unipolar - I measured it,
- Piker controller @24 V w/10 ohm resistor - each phase.

I would like to know how much holding torque it has in a bipolar series and parrallel. I don't have a bipolar board and so I wanted to power it up direct to measure the holding torque. How big should my current limiting resistors be for both series and parrallel?
Thanks for your comments.
