If it is a removeable ordinary type radiator not forming part of an outer radiator grille, i.e.. a bog-standard rad like you find in Cortinas and just about everything else, then you will find that a replacement core is available which has more rows of cooling tubes, and therefore more cooling fins, than those available in earlier days; also thinner tubes so that more will fit in the same length of core. So more cooling efficiency is available from the same core size.
As an example, the Riley RM rads are being re-cored these days using the more efficient core, for around £150-£200 all in.
As uncle Alec says.
I had my 2 minis done, originally they were 2 rows but had them re cored to 3 rows and the same original dimensions were kept but its much more efficient now on the standard mini the temperature sits slightly below normal and on the custom one it just sits on normal.
I have also fitted 2 external electric fans which I switch on from inside the car whilst in traffic and this helps too especially in our hot summer.

My Gentry has a re-cored (BMC) mini radiator with a longer core and I think (because it was done over 20 years ago) an extra row of tubes. It has proved well capable of handling a Triumph 2000 engine. Even towing caravans all over the Country. Even in heatwaves (yes we HAVE had one or two in the last twenty years!). In spite of it being partly hindered by an oil cooler rad. just in front of it.
