This is my first-ever windage plate.

A little background: The purpose of a windage plate (in my rudimentary understanding) is to greatly reduce oil being whipped up into a mist by all of the rotating parts in the crankcase (crank and pistons, mostly). By doing so, the oil remains more separated and you'll have less oil coming out of the breather tube under hard driving conditions (like extended high speed interstate operation). This only works if the windage plate is positioned ABOVE the oil line...which on the V700, Ambassador, and Eldorado requires a sump extension (which I have). After adding the sump extension on my Ambassador, I noticed a decrease in the amount of oil being pumped out of the breather tube. The addition of the windage plate has further decreased my oil loss.

Important note: Any time a sump extension is added to a loop frame engine, the oil pick up must also be extended to reach the new, lower oil level.

The first photo shows the plate by itself on a yellow background...so you can easily see the holes. The remaining photos show the plate mounted on an old engine block I have. The purpose of the large hole extending from the oil pick-up is for the dipstick and for the oil return from the breather.

For the most part, I'm pleased with the outcome. I would, however, make the following changes with subsequent plates:
