Here's my 451 build:

* 1972 400 block
* forged 440 crank (mains cut down)
* eagle 6.760" H-beam rods
* diamond #52007 hockey puck forged pistons
* MP 557 solid cam (.557 lift/296* duration) installed 3.5* advanced at
106.5*
* Cloyes hex-a just timing set
* Harland sharp roller rockers, standoffs and spacers
* MSD dizzy and 6AL box
* Edelbrock aluminum heads (84cc)
* Crane 3/8" pushrods
* Edelbrock STR-15 2X4 inline intake
* (2) 750cfm Edelbrock carbs #1407
* TTI 1.75" headers
* 10:1 compression
* balanced bobweight at 2356 grams

Revs like a mother, will be in the 10's soon, I hope. Would already be
there, but I'm stuck with NSS rules on intakes/carbs/slicks

   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
