Okay it seems your water flow is good , have you checked your timing, if it is not right it can cause your car to run hot
Hi, I have timed this engine, but need to check it again for peace of mind, need to borrow a timming light to do so. I really should buy a timing light, one tool I don't have.......Thanx Fred

2nd Update,
I went for a drive tonight, outside ambient air temp was around 55 or so.
On the highway driving at at 55 mph, the temp remained at about 165 the whole time we were on the highway, when we slowed down in town, the engine temp dropped to about 156, it stayed like that in town, I was even stopped by a cab driver, who turned out to be another old Mopar nut, he has a 1950 Plymouth. The temp remained at 156 while idling for about 10 minutes.
So not sure what to make of these temp results, will see once we have warmer weather, the heat riser is still stuck, hope to fix that next week...........Fred

Besides the heat riser (which may be the source of most of your problem), I would particularly look at ignition timing. Most cars I've run accross are timed at about 6 degrees before TDC with the vacuum advance disconnected and the engine at idle. You mentioned 2 degrees after TDC. I think you should double-check your specs and make sure you timed the car using the proper procedure. Then, with the vacuum advance still disconnected, you should gun the engine and check to see if the mechanical advance in the distributor is working. If it is, reconnect the vacuum source to the vacuum advance unit, rev up the engine and check total advance. It should be much greater than the mechanical advance alone. I have a mid-60s Buick book that lists total advance at maximum RPM in the range of 40-60 degrees.

Well, it's porbably in the 160 neighbourhood, it was a cool evening, so no surpirse.
Today it's about 63, went for a ride, temp was holding steady at 165, it was noticeably warmer under the hood.
I know it was cool out yesterday, as my BBQ was running cool also, the cool breeze can have that effect.
I also notice after todays ride, the carb felt cool to the touch, maybe the heatriser is stuck in the warm postion, I will find out soon , as I will be taking it aprt next week.
I need a day at 75 or better, if I can keep the temp under 190, I will be happy, still need to check the timing and make sure the vaccuum advance is working, a lot of guys I know are pointing at the timimg as a cause to heat up, I am not so sure.............Fred

Just noticed somehting, I came back about an hour ago from my ride, I just took a sample off the bottom of the rad drain to see what it looked like, the coolant was quite cool, while on the top of the rad, it was still hot to the touch, is this normal after an hour oor more of sitting, you would think they would be a uniform temp byt then, maybe this rad is partially plugged, works well in the cooler weather, then heats up in warmer weather, just an idea.............Fred

Beg, borow, or steal an infrared scope. Run the car and scope the radiator, top to bottom, lefat and right. I haven't looked at tuneup specs either, but 2 degrees after TDC sounds odd, I'd rather believe before TDC.

In reference to the 2 degree ATDC timing:
My 1934 calls for that timing, but remember; the fuel at that time had about 60-70 octane, not today's 87 octane. If you use today's gasoline, you need to advance the timing. When I first got my car it too was timed to the factory setting. I could barely make it up my hill. As soon as I advanced the timing I about doubled my horsepower.
