   I had similar sorts of problems with a '75 Olds 350 4bbl.  The
problem only showed up when warm, and WORSE in the winter.  It also led
to stalling at low idle.

   Turns out the problem was insufficient voltage to the plugs, because
of a problem in the EFI chip.  Upon replacing the EFI chip (which tested
OK according to GM's nifty EFI chip testing machine!), all ran well.

   The reason for the increasing effects in the winter was changes
in composition of gasoline in the northeast during the winter.
