Pulley Diameters

Ok a few questions. I'm having heat/cooling issues.
Here is a pic of specs from my 67 manual.
I see the ratio is slightly different. My questions,
1. Isn't the ratio(fan:crank) meaning the fan pulley is bigger than crank pulley?

Those manual specs are confusing IMO...I think the fan pulley should be smaller than the crank pulley.

2. C, what size pulleys did you decide on?

Last update was 6 1/2" crank pulley & 5 3/4" water pump pulley. Still not good enough & working on it.

3. Wouldn't a larger pulley speed it up, as opposed to the smaller pulley?
Thanks

Just the opposite. This has been a learning experience as well as a pain...LOL :eek:
