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.

Subject: 273 Swapping Sides on Pistons
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.

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
