Thanks Andyd, I like lots of details.
When I test fit the engine and the Mast pan I created a new clearance issue. The left front portion of the pan didn’t clear a steering rack fitting. I had to cut out a small notch and create a piece to go back in place to clear it.

Next up was to create a trap door baffle for the pan. I started by cutting out the cast baffle in the pan. Then I started with a Improved Racing baffle for a Holley pan. The first issue is the Mast pickup is clocked 180 degrees opposite of the Holley so this meant the lower part of the trap door had to rotate 180 degrees as well.
Here is what I started with.
Here is the Mast baffle laid over the Improved Racing trap door.
The pickup difference. Mast on the left, Holley on the right.
And here is what I ended up with. It took way to much time to make this piece.
While fitting the pickup I decided to make the little hold down to use the second bolt on the oil pump. You can buy these but I was ready to button up the pan and didn’t want to wait so I made this one out of some scrap metal.
Before buttoning it all up I ran the Pan, and baffle through the dish washer to give it a good cleaning. Since it was not oily the wife approved. She has gotten used to parts coming into house for various reasons over the years.
