Manual rack and pinion

I'm changing over to a manual rack and pinion over the power steering rack in my 50 Ford and was wondering if anyone knows the ratio difference. I've read manual is the way to go.

 

so, exactly what set up do you have now? different ratio available for racks.

 

I set up with a power rack from a 90 Cavalier center steer but after reading about guys using manual racks and how happy they are with them i'm changing to a manual 90 Cavalier rack. I like the idea of a cleaner look over adding pumps and lines. I'm sure the manual must be geared different than a power. Power racks seem to have a quicker steer if i'm right. I guess i'll find out when i put it in but i was just wondering what to expect.
