My car is not back in one piece, so I cannot say for sure that this is the problem, but when I cleaned the block I was amazed how much debris was in the water jacket. No liquid came out of the drain plug at the back of the block, and when I removed the core plugs the rust coloured sludge was like a small wall behind them. After a lot of poking with screw drivers and bits of wire I used a pressure washer followed by some proprietary coolant system cleaner. I think/hope it is now clean.
An Australian friend ran these cars back in the 1960's in the Sydney area and did not have an overheating problem, and it is a lot hotter there than here.

My “built” Stromberg engine had a tendancy to creep up the temperature scale while idling in 85°F + weather. I replaced my non-standard copper “fat boy”(?) radiator with a full-width aluminum Cool Experts radiator, with two Cliveyboy-supplied Revco (I think) puller fans and a Cliveyboy thermostatic fan control housing.
So far this solution has been perfect. The engine now stays just below 180°F even in 95°F + temperatures.
I don’t know where you are, but all of this is UK stuff.

My hardware solution is
3-core Triumph radiator
70º C (160º F) thermostat
electric pusher fan, always on
good radiator cap
coolant catch tank
blocking ALL holes, over and under and on sides so all incoming air is forced through
The software solution, applied periodically, is
cleaning out radiator, core, engine block and hoses with Thermo-Cure ($15-20 at Walmart)
filling cooling system with clean tap water
using a cooling additive like WaterWetter or Hyperlube Super Coolant (I'm trying this now)
I reapplied the S/W solution this week and drove for several hours yesterday ambient temp at 85º F and the coolant stayed under 90º C.
I had problems with GM long-life coolant so now am running without anti-freeze and depending instead on the corrosion protection in the Hyperlube additive. I live right on the coast in So Calif and h*ll will freeze over before this car will be in sub-zero temperatures.
While I was messing with the coolant, I also checked the chain tension and readjusted my doors. But that story is for another day.
