Forward Facing Sump
I used a magnesium sump off of a IO-360-C1C on my PV 360 but had to fabricate/modify custom intake tubes to fit the engine as well as my 4’s cowling. 2 options you do have without doing any fabrication would be the Lycoming M1B Intake tubes which adapt Lycoming’s A1A/A1B6 Sump to a 360 PV engine. The second option would be to use the Superior aftermarket cold air sump which has 3 different sets of intake tubes to fit either the 320 PV, 360 PV or the 360 Angle Valve. ECI use to have a forward facing sump for the PV engine as well but don’t know if their still being produced. Sky Dynamics makes some beautiful very light weight sumps and intake tube combinations as well, primarily for the aerobatic crowd.
When I built my engine these options weren’t available. Now You have multiple options but none of them are cheap !!
I see your flying a 4 as well which makes it an extra challenge that will probably require some cowling mods. The Sky Dynamics Sump may fit within a stock cowl as I’ve seen them on 4’s before.
