pass port

Has anyone ever smogged a large streetport and passed? What did you do to make it work?

everyone's idea of large is different, some people port the primaries larger than the stock secondaries and double the size of the exhaust port with squared off edges... those are more of a race port, a large street port should pass fine with a good quality cat converter and fine tuned fuel system.

for example i built a third gen with a moderate street port, new main cat, no precat and tuned with PowerFC and it ran 2 Hc at idle and 1 at 2500RPMs, that is cleaner than it was when it rolled off the delivery truck 15 years ago.

unless you go drastic overkill on porting then it will not have a huge impact on emissions so long as everything is functioning well.
