I'm facing the problem of routing throttle and mixture controls
around the Style V exhaust on a 180 hp engine with the forward facing
induction modification on the sump. At present the sump has no tabs or
bolt holes that can be used to support brackets for the controls. Do any
of you who have addressed and solved this problem for an IO-320 or
IO-360 have pictures showing the cable routing and brackets supporting
them? I'm using the Airflow Performance injection unit.

Charles,

 

I don't have the airflow unit but my sump did have two studs on the bottom about mid way.  I fashioned an angled bracket and small plate to capture the throttle cable end in the usual manner.  The mixture control cable is fastened to a bracket on a right front sump to case bolt.
