Rich,
I don't know what year they started using side mounts, but you can get a 
"ZZ4" short block (or most other production small blocks) from your local 
Chev dealer and it will still have the front mounting bolt holes.  ( that's 
what I'll be using in my '56 napco 4x4)  The new breed of SB's don't have 
the front holes anymore (98 - 99)

<<<Hey All,
Does anyone know in what year did Chevy start including side mounting on
the 350, and what year they stopped providing the front mounting holes?>>>
