Looking into stroker
I have exhausted my search into F/I. Now I am thinking that bigger displacement is what I need. Weekend street only LS3 wanting 500 rwhp and CARB complaint. I am looking for a more consistent power curve across the RPM range. Not sure about headers but gotta pass the sniffer test for sure. Will the stroker engine do this for me with the right size cam, or are the stroker's not carb legal at all regardless of cam specs.? Like I said I am just getting into this avenue of thinking.
Thanks for any help.
PS I have 8 to 10 grand to spend.

In Ca I dont know how you're possiblly going to make 500 whp and still pass emissions. Youre going to need a cam and headers(I would think) and in that liberal state thats going to disqualify you from passing. I did all the research, stroker v supercharging and ended up doing a Vortech. It idles like stock, retains great fuel economy, drives like a totally stock C6 and you wouldnt even know its there except for a slight whistle at 1000-2000rpm. When you put your foot down about 3000rpm it starts turning into a monster! By 4000rpm its putting you back in your seat like you have 100 pounds of weight on you chest. 5000rpm and up absolutely vicious acceleration! Let off the gas for the red light ahead and it turns back into a normal Corvette. Dr Jeckyl/ Mr Hyde. If I were you I would reconciter a Blower.

Yup , as helpful as all your comments on FI when the man is asking about a stroker. I have no idea when somebody asks an honest question why people need to try and push their preference. He exhausted his FI search, and now wants more info. Since I have both I can comment on both. What is your C6 stroker experience?
The stroker will get your there, heck you can get there with the stock displacement, but the emmissions is where you will have an issue. Mine passed in New Jersey with headers, but that's not California. I think the best person to ask would be a California tuner like Andy at A@A who is used to Cali laws. He can probably tell you if you increase cubes and run a small cam, will you meet your goal and still pass. There is no question about power, its all going to be based on emmissions. Strokers are fun, but harder to make power than simply slapping a blower on. A 500 horse n/a car will just about always stomp on a 500 horse blower car.

At least I made a attempt to help the man. And I have driven S/C as well strokers and went wth the Vortech after much research. You on the other hand are happy to make a silly useless comment and add a goofy smile which adds nothing to the discussion. But Im glad to see your second post actually offers some thoughtful information.

An L92 headed LS3 stroker and a Z06 exhaust system will hit 500rwhp with a 230 XFI cam.
The entire install by me is 9k including all parts. PM for details if interested.

An C6Z with a CAI, ported intake and TB, and tune, will make 500 rwhp or very close to it with stock cam and exhaust. So your goal is possible. I'm not saying build an LS7; I'm saying you can get there with a larger engine and good heads. Me, I would give serious consideration to an LS7-based swap, as it will "look factory".

You've convinced me to go uncover my vette and go for a weekend drive.

It will easily pass the sniffer and there will be no outward sign that the car has anything done to it. It looks 100% stock; you cant tell the motor is a stroker and the LS3 heads and intake manifold look 100% stock.
The cam is a 230 XFI....small.
