When I restored my BT7 I put in a high efficiency core, for rows I =
believe. Nothing was difficult. The top and bottom will accept the core =
and almost any competent radiator shop can do the work.

One caveat, I had to flatten the inside of the rail and bend it to =
accept the wider core. Again, that was not difficult. It is hard to see =
the modification.

I had the same options when restoring my Mk1 BT7. I looked into aluminum =
radiators extensively to see what the benefits might be. Contrary to =
popular belief it is not better heat transfer properties of the =
materials. The copper radiator fins on the original Healey radiators =
have much better thermal conductivity than aluminum. The advantage of =
the aluminum radiator is the manufacturing process and the formability =
of modern aluminum. The result is more tube and fin area. I estimated a =
Wizard radiator has about 25% more fin area than the stock radiator. The =
greater the fin area the better to expel heat.
=20
Having said that, there is a third option which is to replace the =
original core with a high efficiency core. This retains the stock look =
of the engine bay and will be close in performance to the aluminum =
radiator. The high efficiency core option will be more expensive than a =
Wizard radiator and the difficulty is finding a radiator shop that can =
access the core can do the work.

My 100 radiator is in need of some rehabilitation. It either needs to be =
boiled out, which would not replace some of the damaged fins, or =
re-cored. I am leaning toward re-coring but that would be more =

Besides price what are the pros vs. cons of these options? Does anyone =

radiator?
