Hello listers,

What goes into the big threaded hole to the left (towards the back) of
intake #2 (right hand side, towards back)? I have a plain old bolt
that came out of the same hole in my old block... when I go to thread
it into the new block, it hits something inside before it snugs all
the way down.

If I remember correctly, it looks like the same kinda hole that
accepts the oil temp sensor in front of intake #3.

Thanks! It is, quite literally, the last bolt that needs bolting
before this engine gets started for the very first time!

Mike.
