question on exposure

Hello all!
I am new to pinholes and I have a question on exposure I was hoping someone
could answer. I am in the process of making a camera with a .34mm pinhole
and a focal length of 75mm. I want to use illfochrome paper instead of
negative or film. I can't figure out my exposure because I don't know what
ASA to rate the paper. Does anyone have any tips that would help me to
determine my exposure time?
Many thanks in advance...
