The oil would pool in the bottom cylinders- WHICH is why before starting they would run the motor over manually walking the props around by hand to detect a cylinder with to much oil in it.
You needed a reasonably intelligent person to do this as it didn't take much to pop a cylinder head off the engine - which basically "rescheduled" the flight, and somebody got to peel potatoes for a week.

This is a pic from the Kaiser Frasier archive of one of the earliest C 119. It was -at the time- the biggest flying transport in the world and continues to this day in service as a water bomber for a Forest service. If you want to see one in action rent the newest "Flight of the Phoenix" movie.

Think that is the back of the engine and it looks like a big flywheel is on the front or as you say- "I'm WAY to close to this operation"
Think that old boy just might have done this before.

Or not, those tank/landing craft engines all came with a big fan and a giant clutch on the shaft end as well as tin to direct the air around the cylinders and baffles between each cylinder, maybe idling in the garage doesn't heat it up enough for him to care but it wouldn't last more than a few minutes making peak HP down in an engine compartment.
Remember our favourite "prop driven beetle"?
Here's another Continental W-670 with all it's cooling system:
The Guiberson was interesting as it had a separate injection pump on each cylinder head, even more challenging if it ever ran away

Where was this Continental W670? Looks like PNW (I hope!?) - I am looking for clutch parts for some of my Guibersons that will be going in this little beastie... And that vehicle mount frame with clutch fork is also on my wanted list. The Guiberson T-1020 and Conti W670-9a are interchangeable - both were used in the M-3 Stuart tanks and then in the LVT-1(A), LVT-2 and LVT-4, 4(A), 5(A) series landing craft during WWII.
The Guiberson actually has an injector for each cylinder and then all the fuel pumps mounted on the case - a 4 lobe fuel cam ring lifts the roller tappets for the pumps and it is geared 1/8th engine speed. The pumps are unusual because they are variable stroke vs the bosch fixed stroke, variable displacement.
I have 4 of these engines and am working on bringing 2 back to life.
Enjoy
Matt
