So did I.   It's my understanding that the OHC 6 block has no 
provisions for a camshaft, lifters, or pushrods.

That I didn't know...   :)

It has a lot to do with the production machinery.
It is quite important to be able to make the new
engine on existing equipment.  Everything from
the boring of the blocks, machining of the crank 
and camshafts, and machining of the heads is
affected.  The factory also has to be able to go 
back to the old engine parts for service parts so 
the bore centerlines are held.  The block itself can 
be quite different as is the OHV engine.  I do not 
know about swapping cranks but I would not be at 
all surprised.  

The Chevy 292 block is specific to trucks and as such
is made with heavy cylinder walls which allow a
considerable overbore ... never did it myself but there
were tales of using 6 Lincoln V8 pistons.
