Neal,

Nothing to stir up here, your right. But Chuck is wrong about the
440 not being able to live at 650 HP. If built right, it will last as
long as a stock block 400 at the same HP.

OK, this is sure to stir up a hornets nest, the lowly low block, the
400.
   It is hard for me to find the 440, i have only found one around
   here,but  at the same time I know where three EARLY 1971 or 1972 400
   engines are and one ofthose still has its original bore. The price is
   much less too. 
   In one book I have  "Big block MopAR PERFORMANCE" BY cHUCK sENATORE
he
   says some pretty intersting stuff about the lowly 400. 
  A) The block is stout and can take the punishment of over 650
  horsepower, whereas the 440 cant.
   B) He claims " any engine that can be built in a 440 block can be
   built better in the low-deck 400 cid block. This is due to the 400s
   shorter deck height, which allows for a lighter piston".
    C)You can turn down a 440 crank and get a 451, turn down the rod
    journals and yield a472 or use an  aftermarket 4.15 stroke crank and
    get a 496. 
    D) He says the 451 combo is basically a 440 with a lighter set of
    pistons, and therefore "expect to gain about one to two tenths of a
    second over the same combination in a 440."
   E) The 400 is slightly lighter and affords u more engine compartment
   room and hood clearance  because its slightly smaller
    What gives- I always thought these were crappy motors that your
    grandpa had in his Cordoba.
