The two bolt holes in front and the two at the back didn´t line up when I made an paper copy and tested on my Megablock, so check those out.

here is the drawing that I sent to Alan.
I also sent an DWG and DXF also.

I got the PDF drawing from a Moparts member, don´t know where it comes from.

I did some quick measurements on a 1977 block and they were within about 0.015" of that drawing. I didn't make an oil pan, but a jig that mounted to the various holes and it fit well between any pair of holes. For example:

Drawing Mine
4.200 4.187 between the holes (large spacing)4-3/16
2.700 2.687 between the holes (small spacing)2-11/16
2.740 2.756 between the holes (ends) ~2-3/4 = 2.750
0.580 0.580 side offset rear holes ~37/64 = 0.578"

I didn't use the front holes, but I just went in the garage and made a quick side offset measurement and 0.460 looks like it matches that drawing (1.140-0.680=0.460). When adding up the spaces, the drawings 4.20 and 2.70 fit better then the fractions I used.
