I found a good article about balancing:
http://www.carcraft.com/howto/ccrp_0803_engine_balancing/index.html
So if an externally balanced 360 needs a new harmonic balancer, flex plate
or flywheel (whichever the counter weight are attached to), does the new
part have to be taken to a machine shop so it can be balanced to match the
existing parts?
and which part does a 360 use to balance?
Thanks,
James
