If you have an upgraded cam and you live in cali please post up what you have and if you can pass smog with it. I want to go semi radical on my 5.3 but I have to try and pass smog come april next year. Is there any way to possibly just get the cam I want like a 224/224 560+/560+ 112 or possibly a little bit bigger and still pass emissions testing? Maybe have keep 2 pcms laying around one with a very very conservative tune that can pass smog standards and then another for performance when I dont have to worry about it?

 

From what I understand 224-226 is about the most you can get away with.

 

on what lobe?

 

I've heard that a 220/220, tuned properly, will pass. More than that and you better have a killer tuner (and say a prayer while you're at it).

 

Definateoy not more than a 224 in a 5.3.
