Bill,
I've electrolytically de-rusted milling machine parts, and I don't expect
your method to work very well.  The electro field needs to be pretty direct
between anode and cathode, without any shielding in between.  I suspect the
various contours of the engine block will cause exactly that shielding,
leading to lots of areas with no appreciable de-scaling.

I recommend, instead, find a steel tub big enough to submerge the block.
Use a big propane burner ring to heat an alkali solution to near boiling,
and let that do your work.  Of course, it's probably easier and less
expensive to haul it to a professional shop to boil the block.... :-)
