<div>Gotta remember this engine was used in several different vehicles, some of them diesel fueled. These features could have been needed for other applications. I suppose the extra hole could have been for a relocated dipstick or maybe an oil cooler return.
I thought about it for my PVC mod, but decided on the down tube port instead.</div>

<div>Not sure what it's for, but it does exist on my engine and the plug that fills that hole uses a 1/2 BS or 7/16 WW socket. Again not sure what it's for. But I'm pretty sure if you don't plug it, you're going to have some problems.</div>
<div> Also look at the back of your block, there is a hole that used to fit an oil feed that was eliminated on 100 engines, but is used to feed oil to the 100S distributor I believe. The hole wasn't plugged on my block and I didn't notice it until I had the
engine back in the car and fired it up and it leaked oil out the hole. Standing behind your engine, it's a little off center to the left and about an inch below the head. I've been told it should be a brass plug. I made an aluminum plug and pressed it into
the block.</div>
