A Fan shroud is extremely important to proper cooling. If you can get one on make sure that it covers the radiator core and that the fan is half way in. The fan should fit with only enough room to clear the fan.
Also depending on the radiator try to use a cap with as much pressure as you can. For each pound of pressure the boiling point rises significantly.

Have to look tomorrow, can't remember. For sure no addition of A/C to the car.  But I will say that I have tracked the temperatures for three years and of course June-August is when it ran the hottest (not that drastic but hotter then I prefer) when three times it got up to the 210+ mark and twice up to 220-227 degrees and these last two were while idling.
The radiator is one of those types that rather than the temperature being hotter at the top and cooler at the bottom, it reads hotter on the driver side and then noticeably cooler on the passenger side based on the hand hold infrared thermometer.
I would go with a pusher fan if there were room. But overall, it's manageable and we drive the car a significant amount on short tours, to shows, and displays.

Doc, if your radiator is hotter on one side than the other it is possible that you may have some clogged tubes in the radiator.  A radiator shop can fix that problem.  My '48 Frazer reads hot on the gauge but when I pull over to let it cool down it does not seem to be boiling and cools down quickly.   I think that may indicate that mine is really cooler than what the gauge indicates.

I guess there was some confusion about my fan and shroud statement. The fan should fit into the shroud with about 3/4 of an inch of clearance

I was looking around last year for a shroud I could use but just didn't follow through...another item for the to do list. I agree, a shroud would be beneficial.

Yes but be careful about boosting the pressure, check what the radiator will take. Also I have found that flex fans are not as effective as steel fans they may be a little quieter but not as good for cooling.
I will try to post a picture.
Need to do it from my desktop won’t work from iPhone.

Are you using a 4 or a 6 blade fan? Darrin 502  brought up a good point on that making a difference..

This is a 7-blade fan.

[Doc]

Steel.

Totally agree with Lee regarding the flex fans...tried them on my Ford Y-blocks and were horrible!

[darrin502]

also not crazy about clutch fans the after market ones are junk. If you want to use one get one from a new car dealer they are more expensive but they work.

I used a 6 blade steel fan. There are universal ones out there that fit any bolt pattern some times you have to open up the center hole to fit.
