I have my 83 F250, 460. It's GVRW is 8600. It has no Cat.

In Oregon they say that any car 1975 and newer has to go through DEQ (in the areas where DEQ is done).

But I've heard from people who have similar trucks in Portland, that they don't have to go through DEQ because of the GVRW. Although the stipulation on the website is Diesel engines.

Does anyone know whats the deal?
