i have a stock o1 reg cab 5.3 a4. i live in the bay area of ca. ive been reading up but cant find someone who has said that they have passed smog with a bigger cam in ca legally, all ive seen is the he said this bs. just looking for some real answers. i understand if it has to be tuned. if its been done, which its had to of been. whatcha got?

 

224/224 on a 114 seems to be to be the biggest cam that can pass smog. Bigger cams have passed but it's all in the tune of the truck.

 

Hey Stocker,
welcome to another Bay Area member! I have heard of cammed cars and trucks passsing smog but dont know personally. My tuner says it shouldn't be a problem with the right tune.

Like above the 224/224 114* is considered max.

Not related but if you dont already know, a bunch of us are getting together at the track for a day of racing, barbeque and meet on the 17th.

See this link for details. Hope you can make it

 

hey thanks for the welcome trever1t. i went to the meet in oct or something like that. to bs a learn a little, talked to the hippie kid(forget his name) with the blue extcab that synergy tuned. his never passed smog. never got the chance to talk to rick. i guess i just need to start making phone calls to tuners, it just hard to believe people that are in it for money and its not there ride.

Tuning is a business, but you have a lot of choice. You can Dyno tune like we do at Synergy for big $$ or you can get a less expensive street tune or mail order tune.
Justin has heads, long tubes and a 226 cam which would make passing smog difficult. He is going back to a stock Radix setup and will have no problem passing.
Come on up on the 17th and run your truck!
