Thanks Jim, its neither of those two - its the L60 belt driven alternator
that replaces the standard Auto alternator from the front of the engine..
I also have installed the SD-8 as a backup on the vacuum pad.
The documentation did not say anything about cooling for it either.

Which B&C unit are you installing----the SD-8 or SD-20? The SD-8 is
driven off the vacuum pump pad at the top right rear of Lycomings
accessory case and I think the SD-20 is also mounted there. They are
both PM units with external regulators provided. The SD-8 is happy
without any external cooling air provision. Don't "think" that is any
different for the SD-20.

That's because there are no installations on the
front of a Lyc where cooling has been identified
as a critical or even questionable issue. Hence,
nothing in the instructions about cooling.
