Engine temp rises when I get to cruise speed

Joe, did you do anything else after you switched the Aluminum radiator?
I'm wondering if you have brakes dragging. smell and touch test on the brake drums will tell you this. The fastest you go the more this and air resistance will drag on the engine.

No changes were made after I installed the radiator. I have the MT 11" Lincoln style brakes up front and drums on the 9" rear. All adjusted well.
 
I took the car out this morning
63 degrees 61% humidity

I'm using a digital stop watch for the times listed below.

I started the car and let it idle. NO FAN.
4 minutes the temp was 150 degrees.
At 5 minutes, 30 seconds the drivers side t-stat opened
At 6 minutes the temp rose to 170 degrees
At 6 min/30seconds the passenger t-stat opened.
The seconds are approximate, but very close
8 minutes in I start to drive to the high way which is a couple of minutes away temp is 175
8 min/30seconds I hit 180 and turn on the fan. I got nervous!
9 minutes I reach the high way and turn off the fan. Fan was on for approximately 1 minute.
I drove on the high way for about 13 minutes at 60-65 mph at 180 degrees.
Got off the high way and hit the back roads for about 12 minutes at 30-45 mph and temp hits 185
Back on the high way for 14 minutes still at 185 and NO FAN.
Get off the high way for a short stop and go ride to my house and I hit 190 degrees as I pull in the driveway
Total run about 50 minutes.
It really like 63 degrees!

HAHAHA!! As frustrating as this is, I really can't complain about seat time!
I'm really chasing about 10 degrees. After the T-stats, I was thinking of changing the pumps. I found out that they're Speedway pumps not Skips as I originally thought. I personally don't think the Speedway pumps are a problem, but process of elimination is key. I sent cores to Skip last week so I'm just waiting for them to come in. The saga continues!
 
I'm guessing you have boiled a pot on the stove with a thermometer to check when your thermostats opened.

Some guys are using volvo stat's as they fit and open at 170.

190 wouldn't bother me. Glad you are driving it and flushing the gremlins.

In 63 degree weather? What would it run in 95 degree weather?

Warmer. glad it's 63 in NJ.


Might be understanding Brassworks response a bit better now.

Tinker I put then on the stove and saw they opened at about 180 degrees. (these are 160 degree t-stats) I don't know how accurate this test was. I really just wanted to make sure that they did open.

I took a quick test ride yesterday with the Bob Shewman stats. They look just like my old stats except there's 4 holes drilled through around the perimeter.
It was 90 degrees.
Here's the timeline:
5 minutes idle, no fan to reach 150 degrees
6 " " 160
7 " " 170
Start to drive at 7 minutes. Driving was stop and go up to 30 mph.
8 minutes in it went to 180 degrees
10 minutes in it went to 190
I put the fan on at that point.
15 minutes in I was at 200 degrees
Pulled car back in the garage.

I should be able to get some better info today with some high way time also.
 
I don't want to bore everyone with the details, but it was the same.
Start the car, drive the car park the car.
It was 75 degrees outside, temp was fine until i got on the high way and it went to 200 and then drops to 185 on the back roads

With all the work and time you have invested trying to make the brassworks radiator results better, why not put the ugly aluminum radiator back in and drive it.
Mount it on the wall and put a dartboard on it.

My .02 cents
