I have used standard and modern film cores on many sevens over the years and have never had any problems with overheating. My experience of Austin 7's that overheat is that there is usually an underlying problem of carburation, timing, type of fuel etc. The standard thermo-syphon system appears to work well on the vast majority of trials Austin 7's. If the car is going up a 30 degree gradient it should work even better!
The only time my saloon has ever overheated was when I was using cheap supermarket unleaded petrol.
I can vouch for Steve's trial car, generally the problem was getting the engine warm enough. I have always run with the standard 2 blade fan with the fan belt quite slack.
