I'll answer that, based on my complete redesign & construction: First off,
in Tom's case, he didn't want to build a new HVAC box, which would be
required to provide room in front of the existing box for the blower.
He might, of course, have hung the blower below the box and only had one
bend in the air flow, but that would have partially obstructed the radiator.

Most importantly, for Tom's and My mods: The problem of providing supply
air to the blower. With the blower out front, where we'd really like it to
be for most-linear air flow, one would have to provide ducting from the
cockpit out to and completely surrounding the blower. A BIG fabrication
job.

If you look at all of the dual blowers, you'll see that they all induct air
to the wheels from both sides -- the outside and around the center-mounted
motor. I seriously consider closing the motor side and using round ducts
into each side, but finally figured out that the wheels would be seriously
starved for supply air.
Among other strikes against the idea.

Tom, feel free to supply your own reasons if this doesn't cover it.
