Revotec makes a "Y" splitter..

In-line Blower Fans =E2=80=93 www.revotec.com | Automotive Cooling Speciali=
st
<https://revotec.com/product/in-line-blower-fans/>

<https://revotec.com/product/in-line-blower-fans/>I don't know if there is
enough room, but you may be able to run one hose to the cold air box and
the other hose underneath to the float bowls. You'll have to mock this up
to see if it could work. I'm thinking that the steering shaft may be in the
way.

Alternatively mount the blower motor lower and bring a second hose up from
below. I can't access my car right now so I don't even know if there is
room.
