I'm considering a cam swap pretty soon and I was wondering which ones will pass emissions testing. I have heard the LS6 and the GT2-3. Are there any others? It would be into a 4.8 and I live in Houston, TX if that helps. If this has already been posted just let me know, I did a search and didn’t find anything.

 

they wont hook you up to the sniffer in houston. as long as you dont throw any codes you should be fine.

 

really? I didn't know that.

Thanks,

In Ca, a 224/224 114* is generally recognized as the limit to pass the sniffer.

 

well thats cool to know you can go that big and be ok. does the lsa need to stay 114 and up?

 

you guys think a 220/220 would be a good cam for a 4.8? I've seen a few guys running it. if not what do you suggest for N/A.

 

i know 04RST is running that size cam by Thunder Racing and is happy with it i cannot remember what LSA his is though...
and in new york as long as a 97+ vehicle is not throwing codes and passes the visual inspection of the brake and all then you can pass the inspection

 

if your not wanting to go with a bigger stall converter I would suggest the 2k vette cam 198 207 500 500 115.5, nice little cam and I picked up .3 in the 1/4 with it. send me a pm if you need some help.

 

that 220/220 on a 112lsa would be a perfect cam for it, and should sound good aswell...

 

stick with a smaller cam unless you do a converter. the biggest one i've heard of for the 4.8 and 5.3 with the stock converter was the comp 216/220, anything between the zo6 cam and that would be good though.
