any known smog problems with 93 dodge dynasty 3.3?

This is a 20 year old car- that's like 200 human years old- First- it passed the smog test so why worry? Secondly, a car as old as yours will have a general degradation of all the parts in a system, so it's likely that you won't be able to bring your engine up to perfect smog levels just replacing one or two parts- Finally, I LIKE your idea of a "good blow out"- this is called an "Italian Tune Up" and a lot of times it woeks wonders with a car that is only rarely driven- how does it work? Think like an Italian race car driver at Monza- floor that baby, race it, get it up on the freeway at night and find out what the top speed is- of course, don't exceed what you feel is safe- the advantage of the Italian Tune Up is that it is cheap- and a bit of fun, too
