Joey,

They made 230 blocks through 72, they only made the thick web ones from
Apr 71 to Oct 71. Those are the date codes to look for.

Earl

   I think the real difference is the web thickness in the early (230) 
blocks.  The webs are almost twice as thick as a 440 block, thus making
the block 
theoretically stronger, as well as being about 65 lbs lighter.  Neal, If
you can 
find the 400 blocks ending in the casting number 230, buy them all and
you 
will never lose money.  They only made them for about 8 months.  As for
building 
a 400, they were cursed as a smog motor with low compression, sometimes
as 
low as 7.6 to one, to run on whale oil.  They respond to nomal
modifications.  
Aftermarket high compression pistons are lighter, the 400 rods are
shorter, 
lighter and somewhat stronger than 440 rods.  If you have a 440 crank
turned down 
it will be lighter. and the engine size is physically smaller to fit in 
engine bays that normally have fitment problems with headers and
starters.  A 
properly built 400 stroker will rev like a small block and make hp/tq
like a big 
block, and will cost just a little more than building a 440.  This is
due to the 
crank work which cost me 300.00.   Go for it!     Joe
