I hope that's not a surprise to you. The first loop (block2) involves
two calls into the AutoCAD COM object in each iteration. The second
loop (block3) is simply manipulating lists of integers, entirely within
Python.

There isn't really anything here to speed up. You're just "glue". The
work is being done in AutoCAD. It is almost impossible for me to
believe that Visual Basic does this same loop any faster.
However, you can certainly try switching to early binding by using:
acad= win32com.client.gencache.EnsureDispatch("AutoCAD.Application")
