I tried the search feature and couldn't find exactly what i was looking for. Does anyone know the largest cam to pass emissions in california? I spoke with a gentleman today who claims if i use ls1edit, i may be able to get the blower cam i am looking at to squeak by with what he called a smog tune.
Camshaft - 232"/236" .585"/.598" 114LSA aggressive profile with a 2800-7000 RPM range, rough idle, for blower/nitrous applications

Thanks guys for the information, i appreciate it. I've never had to deal with smog before, but since i'm moving to california in a few months i'm going to have to. JRP, thanks for the advice on the search.... found exactly what i was looking for. Thanks again...

TR224/114 will pass for sure WITH a tune. Pretty much any cam you get will need a tune to pass and for more power. Some don't need a tune, but it still a good idea to get one. That cam WILL NOT pass by any means other than a miracle. 224/224 is safe and pretty much the limit. 226/226 is getting VERY risky. The TR224 cam is a great cam and many people have it including myself. I love it and so do many others. At the bottom go into the Western forum and there are some CA cam threads in there also.

Check to see if your county is going to keep the dyno-test and not switch to the OBD-II testing. Some counties/states are switching from the dyno test to the PCM scan test. That is exactly what happened here in Lake County, Ohio(basically just east of Cleveland). Ohio had an emissions test for a long time but the test was only some small service station looks under the car to see if the cat is there and then make sure you have a gas cap....that was it! Then Ohio got this bright idea of "E-CHECK". First off they make sure there is/are cats on the car. They put your car on a chassis dyno, run the car up to 55+mph while testing the tailpipe emissions; they also test the emissions at idle. After that they test the seal of the gas cap. They have had this for years! Just a fews months ago Ohio switched to OBD testing. They scan the PCM for faults and codes. So it doesn't matter what mods you have as long as the PCM is tuned right. If CA still has dyno testing, why not just use nitrous? Can we have the specs on your car as of now?

Cali guys, it gets worse....................
Some counties here are now looking at the OBD2 self diagnostic tests to determine pass/fail results. Not only does the car have to pass the tailpipe test on rollers at 15 & 25mph, it also has the gas cap test and OBD2 diagnostics. There are 5 tests (6 for EGR cars). I believe most of the available scan tools will show test status of the 5 or 6 different diagnostic tests. Many cars with aftermarket cams are not completing the "catalyst" test. This will result in a failed test and the car is considered "noncompliant". That means no registration renewal.
Somehow the aftermarket is going to have to get ahead of this or lots of people will be putting stock parts back on their cars every couple of years.
Any input about this subject is very welcomed................
Good luck,
Richard

Not really sure where reseda is located but i'll be staying with my girlfriend in vallejo. She said when they smog her car they just ( her words) stick this thing up the tail pipe of the car, i go have a smoke, and after about 10 min they tell me i passed and that's it. She did say they run the car, give you a print out, and the info is forwarded directly to dmv from the machine but that's it....no rollers or scan hook ups according to her. Maybe emissions testing varies from county to county out there, but this is all new to me since i never had to worry about anything like this before. Personally i think it's

The aftermarket companies may just have to spend the money to get carb certification on all their products. This will cost them big money in the short run, but may wind up making them more money in the long run. As you stated if it get's to a point that they get so "tight" with the emissions laws that you can't even change the factory installed plug to an aftermarket one, then hope all these companies can afford to lose out when people start switching the cars back to stock. This will be especially true if all 50 states implement the emissions laws and get as strict if not more so than california.

Superchief: Vallejo is north of the SF bay area and does not yet test on rollers. The testing procedures vary from county to county. Here in Reseda, we're part of LA county and smog tests are the most stringent in the state or country for that matter. Never the less, eventually all states will adopt the plans modeled in Cali.. So far only the metropolitan areas are required to show compliance.

I'm with ya bro..........
FWIW I saw a Berger ZL1 with 427ci engine sail past the local tests here. Those engines use cams with .600" lift and idle pretty rough. My guess is the duration @.050" is somewhere around 240º. I suspect the PCMs have been alterd by GMMG to change pass/fail criteria. I'd like to see more posted info about this subject though.

I believe Team ZR1 is located in northern Cali.. He knows his stuff for tuning cars to pass emissions. I think he's a member on this board. Look him up when you get here and welcome to the golden state...........
BTW that ZL1 sounds absolutely fantastic with the sewer pipe sized exhaust system.

The bay area now has the smog dyno as does the Sacromento area.
Check out www.norcal-ls1.com when you get into town to find out about the local tuners and any other info you might need.
