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 popula=
r belief it is not better heat transfer properties of the materials. The co=
pper radiator fins on the original Healey radiators have much better therma=
l conductivity=C2=A0than aluminum. The advantage of the aluminum radiator i=
s the manufacturing=C2=A0process and the formability of modern aluminum. Th=
e result is more tube and fin area. I estimated a Wizard radiator has about=
25% more fin area than the stock=C2=A0radiator. The greater the fin area t=
he better to expel=C2=A0heat.=20
Having said that, there is a third=C2=A0option which is to replace the or=
iginal 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=C2=A0than a Wizard radia=
tor and the difficulty is finding a radiator shop that can access the core =
can do the work.=20
