Bob,
As long as the side baffles are fitted properly the fan will not have any
issues pulling air through the rad. The fan does little for air flow at
anything above 15 mph.

<div>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=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 25% more fin area than
the stock=C2=A0radiator. The greater the fin area the better to

<div>Having said that, there is a third=C2=A0option 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=C2=A0than a Wizard radiator and the
difficulty is finding a radiator shop that can access the core
