Hmmm don't know man I've herd of F-bodies with tr224s passing, even untuned through cats over from ls1tech. Don't know if that's possible... but a good tune and you should be ok, that cams not huge for a 6.0.

If you've got stock cats, IDK how you could not pass just go out and get them as hot as possible before you go in, if it is a sniffer. I've heard of box stock trucks in CA not passing the sniffer on the first try because the cats wern't up to temp...

Give the guy a break he has been testing the limits of bolt on's for some time now and just slid the cam in this year...

I didn't get any time to check today whether or not it's sniffer or not due to work, but I should be able to check tomorrow. I have heard you want to get everything nice and hot.
Also, is it normal to have a SES light on with the key in the on position and engine off? Mine does that, but I can't remember if it did that when bone stock. It may have started when I changed to the 2002 operating system. Don't know if the light being on with the engine off would fail me. I have no codes in the system.

yeah, according to the critical poster in here I shouldn't have posted this thread. However, I was well aware of the saying that the 224 114 was as big as you could go. However, the variables are different here, slightly more displacement, different exhaust systems, differing emissions standards between states/counties, etc. They even have a discrepancy here based on your vehicles HP (not in terms of emissions I believe, but higher HP vehicles cost more to register). Just looking to see if anyone has gone through the sniffer with a similar situation to mine, that's all.

You don't have to do a sniffer test in St. Louis any more, just the OBDII test. Just make sure your readiness tests are all complete and you'll be good to go. I had my inspection done last month with my truck with no issues.

If there is not a full on visual inspection, drill a hole in your exhaust well after all the O2's and weld in a bung for a widebandor O2. Open it up and thread in a plug with a small hole drilled in it before you go in. If there is a sniffer. The velocity of the exhaust stream will pull air into the small hole and will lean out your exhaust even further without effecting your tune. Then plug it afterward.
