I have to agree with you because the cylinder is the same angle from the
crank on either bank,,,,,I will check, but doubt that the article goes into that, should be a given and just naturally understood,,,,,,,, smile ask them
when was the last time they bought a set of pistons that was specifically
numbered as to which cylinder they were suppose to be in

Over  there, they're talking about doing it with the Commando domed
pistons,
so  you have to rotate the piston/rod assembly when you swap banks so the
dome doesn't hit the head. What I'm saying is that you dont get the offset

advantage by doing that

that would be the same thing as long  as you did not twist the piston.

If  you find the article, Dodger, post it  on the FABO site, as they wont
believe me when I tell them about this procedure. They all think you just
switch the piston/rod  assembly  bank-for-bank.

Ok hope I am not opening a can of dead worms here, but will tell what I
 was
told many years  ago.......
   to  reduce rotating friction, turn your pistons  180  degrees  when
installing them,,,,,,,,,,,,,supposedly the  story goes  like
this,,,,,,,,,the pin
in the piston is not   dead center, and is designed to create  a very
 minimal
 amount of bind when at top dead center of the  stroke,,,,,this is  done
so
as
to  eliminate piston rattle when the piston is in the  process of
changing
direction at end of stroke..........  the  article that I read  on this
also
said that  the engine would be  noisy compared to the stock build,   but
would not
cause  harm,,,,,,,if someone is  interested I will try to find the
article
and post  it,,,,,,,,,,,,,,, dodger

 Tom,
We  used to do it on big blocks all the  time (flat  tops), but have
 never tried it on a small block.  We  were  always careful not to rev
it
to
much when  the motor was cold but it seemed  that the motors  made  more
power.

Over on the A-Bodies only Board, they are talking about swapping sides
 on
the 10.5:1  pistons on 273's.  I had some  confusion,  but it seems to
make
a
little  sense.  Dome offset isnt centered, so   parts of the piston  may
come
closer to the head in places and more gap   in  others.

  http://www.forabodiesonly.com/mopar/showthread.php?t=84332 (3/4   down
the
page is where part of it starts posted by Russ  (Double   M).

Has anybody on the list done  this in the past and had any  real
success?
What are  the downsides to   this?

 Thoughts?


Thanks
  --Tom
