Ultimate Ca Setup
Ultimate Ca Setup I live in Ca which obviously sucks, but we have to do what we have to do so my main objective is to build the highest output MF motor that will pass the sniffer her in Ca. Before I have my bottom end rebuilt I am going to try to max out the bottom end here in Ca!!!! I plan on buying some as cast 205cc afr heads and have them hand ported to the max along with a custom grind cam that will maximize power and minimize emissions and hope for 470 rwhp. I have all the bolt ons plus a intricitley ported Holley intake man that should maximize the setup. The cam specs are somewhat close to 228/228/.590.590/114. What are the opinions? Real life experiences? The heads will be port matched to the intake and after I think about it there are no real life experiences so how about opinions!!!

I think it would be pretty hard to make 470 NA with stock exhaust manifolds or smog legal shorties unless you went FI. A guy in our car club is making 462 with just a hooker cat back and 8lbs of boost.

I would like to stay with the JBA shorties, mufflex test pipes, magnaflow catback,qtec cutout, if I can. Will my exhaust set up
hurt my performance that much? I was actually going to go with a true dual system hooked up to the mufflex test pipes which would pass the smog test.

Do you want it to pass visual also?? because that matters ALOT.. 
Best sniffer AND visual system would be:
JPB shorty headers
220 thunder cam
K&N FIPK induction
High flow exhaust (Corsa, GMMG, etc)
And they all have CARB numbers..
If you just need to pass sniff (becuase you know someone that will look the other way on the visual) then you can do quite a bit more..

I agree with the F/I
Think about what he is trying to accomplish.
470 RWHP with junk exhaust and a small cam.
NO WAY IN HELL, might not even get there with hugh cubic inches.
You need every piece of the puzzle to get to 470 and most doing it have cams that are 232+ duration. Pimp *** heads, and LT headers.
Dollar for dollar you would be way cheeper going F/I.
Most long block stroker motors are 10,000+ easy, and to go resleaved and stroked your 12000+ dollars. Keep your shortblock, buy a set of 6.0L 2500 dollar heads from Jay @ Absolute speed, or TEA, and then buy a nice S/C setup or Turbo.
Lets take a top of the line and go with a real nice kit from 1/4 mile performance.
6500 dollars and it includes everything you will need to install it and have it running.
So you have 6500 dollars plus 2500 for heads and 150 for a cam plus labor and your done. Run 9psi and put down 470+ all day long. Should go fine for emissions as well.
Just my oponion.

The largest cam that will pass is maybe 224 duration/114ls, and only if you have good stock cats. Forget about headers as those are illegal too. Basically if you want a smog legal setup in CA expect around 380rwhp with the stock bottom end, or 440rwhp if you spend a ton of money on 400+ci bottom end.
Of course, you can always do what you want and put it back to stock every two years.

Nice to see that someone is doing it with a 383.
However that is only 1 example, and I am sure there are 100's of F/I guys making that power.
I dont have a SC or Turbo, and dont plan on ever buying one, so I am defentially not making this suggestion because of my setup, only because this is what seems to work great for what is trying to be accomplished.

supposedly there are cars getting 400rwhp+ hp through stock cats and manifolds at don lee's auto
I am not sure of the custom cam superior auto is using but I know it passes smog (barely) I know it has longer duration than 224 I believe it is a 228/228. They must tweak the tuning to pass smog with that cam but they are doing it which is what counts.
There used to be a guy putting down around 540rwhp through JBAs and a Vortech kit in San Diego. His name was Blown Interceptor. He doesnt have the setup anymore, but it's proof that it can be done. It takes a lot of tweaking though with FI to get everything to work right when you are pushing the blower hard.

RE FI, I think the Vortech kit is smog legal, and I know the ATI kit is legal on Corvettes (not sure about their FBody kit). I'd just do a mild heads/cam setup with long tubes, and swap back to stock manifolds for smog time. You might be ready to sell the car in 2 years anyway so why sweat it. As long as you have long tubes and high flow/no cats I'm sure you can hit 420rw with a 224ish cam.
