As long as the side baffles are fitted properly the fan will not have any i=

Gary,
I had the same options when restoring my Mk1 BT7. I looked into aluminum ra=
diators extensively to see what the benefits might be. Contrary to popular =
belief it is not better heat transfer properties of the materials. The copp=
er radiator fins on the original Healey radiators have much better thermal =
conductivity=C2=A0than aluminum. The advantage of the aluminum radiator is =
the manufacturing=C2=A0process and the formability of modern aluminum. The =
result is more tube and fin area. I estimated a Wizard radiator has about 2=
5% more fin area than the stock=C2=A0radiator. The greater the fin area the=
better to expel=C2=A0heat.
Having said that, there is a third=C2=A0option which is to replace the orig=
inal core with a high efficiency core. This retains the stock look of the e=
ngine bay and will be close in performance to the aluminum radiator. The hi=
gh efficiency core option will be more expensive=C2=A0than a Wizard radiato=
r and the difficulty is finding a radiator shop that can access the core ca=
n do the work.
This website has a good overview:=C2=A0https://usradiator.com/cores
