White smoke usually means water, Black smoke is fuel. If the plugs are white, you are running very lean, I wouldn't drive it anywhere until you figure out why it's running so lean.
What kind of tranny do you have? Older automatics have a vacuum modulator (my wife's '92 Aerostar has it) and if the diaphram gets a leak, AFT will go into your intake manifold and make white smoke. Check the ATF level. BTW, this is supposed to clean the combustion chamber out nicely, but may be skewed to only a few cylinders depending on where the ATF enters the manifold.
mine smokes black or white just when you start it, usually black. i've changed the plugs and rebuilt the carb. stopped for a while but now does it again. I would't get tooo worked up about it my trucks been doing it for a while and althogh it starts hard sometimes it still runs fine. I'm hoping the new Holley 4 bbl. I just bought (but haven't installed yet) will solve all of my problems.
