<VV> Mis-matched case halves

[Sethracer at aol.com]

America has been (and still is) manufacturing things, many made up of other 
 parts. The case halves are, of course each an individual casting, one for 
the  left and one for the right. (Actually a second one for right-side FC 
and  replacement motors)  I don't know the actual work-flow process for the  
cases, but it seems to me that each half would likely have some machining 
done  on it, then the two halves would have been paired, then final machined. 
It  makes sense to me that, during the changeover to the 164 crank-clearanced 
cases,  one case half would have run out of stock before the other. If 
their  manufacturing engineers determined that the early crank would work in the 
 later machined case half, why throw anything away? They couldn't have used 
an  "early" machined case half with a longer stroke crank, but in the 1963  
model year, no problem!

This  mismatched case half thing was just discussed on the Corvanatics 
list,  where it seems it is not necessarily uncommon to find these 
seemingly  mismatched case halves on serviceable and running engines in 
the 1963  FC's.  A fact I'm surprised to learn. I've never seen one, but  
apparently that doesn't mean much -- others have.

Details can be  found in the Corvanatics archives.
