So, this project has been on hold for a while as my next big step is to really learn how to properly tune MegaSquirt, and I just haven't had the time to commit to that.
But, I had a couple hours today which I spent casting a proper delete plate for my distributor. This is my first sand casting using a core (to create the hollow for the cam end).
You'll see there's a little divot at the upper left. This is where I can drill and tap for the oil pressure sender, although I may end up moving that over to the oil filter housing.
That's it for now.
