Here is what I did last night. No dimensions yet, just trying to get it all sorted out. The blueprint has a lot of information, but it is scattered all over. Very big puzzle on small computer screen. My dad is having it printed out so I can hang it on my wall. This should make it easier to see all at once. I'm confused on the bore. The blueprint shows 3.054" bore while written specs I found show 3 7/8". The plans have extra holes I don't see in photos. And there are 4 threaded holes that don't have dimensioned locations or I haven't found the locations yet.

The threaded hole are centered on the 3.875 bore and 4.5625 away. The small holes are steam holes that go into the water jacket and the other are only 2 on the outside of the bores (photo is correct).

Would you mind sharing another set?

Jamie, You should also look here as there was not just one block style made.

Thanks briphaeton. The blueprint bore is so small that the outer casting is smaller than the 3 7/8" bore. I'll need to come up with a way to figure out what the casting thickness is around the cylinder bores.

Does anyone have a really good photo of the bottom and timing cover end of a bare block? Couple of details are a little fuzzy.

Thanks Mike for the links. Every little bit helps.
