Case question for possible location for crank trigger Options

[technicalninja]

What was the original use for the large hole on the flywheel side of the right (passenger) engine case?

Looks like it could have been a good flywheel lock location.

To me it looks like very good spot for a crankshaft position sensor...

What was its original reason for being there?

once you put the motor together, the cam timing and crank timing have the same relationship....basically forever.

You are seeking a way to control when the spark event happens...crank timing can do that.
If you need input for the cam timing on the computer you are using, can't you just base that signal off the crank signal with whatever offset is required and call it a day?

Curious because I am going there on my next build...but I never figured I would need to deal with cam timing because its pretty much just fixed.

I would like to see pictures of the solution...to see how clean it can be.
