whats the fastest CARB legal car out there (non nitrous)

i wanna build up my LT1 but i dont want ANY issues smogging this biatch.Just wanna know whats the best combo and still be 100% smog legal. I know you can pass through the tail pipes with a pretty wild setup but but im talking a full smog inspection.

Get some edelbrock headers ceramic coated. They come with a CARB number. High-flow cat, and a good catback

But ideally a BIG cam through some long tubes into header mufflers.

You don't have a crank sensor in a 94. The biggest smoggable cam is probably a cc305 on a 114lsa or something comparable to it. Superchargers dont affect your emissions.

Was looking at the caprice in your sig. Not too sure on the crank sensor, but I dont see why the cam size would have any effect at all on it.

the crank sensor will detect it as a miss-fire

ok,well ill go more into detail into what im expecting. I want my Camaro to be 100% worry free,i want to be able to drive it and not get worried when a cop pulls me over to try to give me some lame *** fix it tickets and if he does (around here they might give u a fix it ticket reguardless) i want to be able to take it to the state ref and be able to pass an inspection and i want to be able to take it into ANY (no hookups) smog station and pass the *** sniffer test AND that other test where they hook shiet up to the computer and all that BS. Its a tall order but are there any really LEGIT cars like these out there??LOL

theres a guy down here that runs 12.0's and gets an average of 22mpg with a 94z28, he has the CC 218/230 cam, 3.73's, 2800 stall, headers but i dont know what brand, borla catback, no cats

the cats are removable, with'em back on he passes emissions

It was tuned here in NC at Carolina Automasters by Jeff Creech

i'm looking for the same thing you are, a fast daily driver that passes emissions the tune makes a big difference on wether it'll pass or not, so i hope you got a good place to get your car dyno tuned when your done

oh didnt notice your in CA, the car i meantioned above passes in a state where the standard HC reading is 220ppm

I built a 95 T/A for a friend that hit 582 RWHP that passed strict IM240 emmisions. It used a 383 setup with a Vortech S-Trim and aftercooler.. I have read one guy here hitting much more h.p. emmisions legal.

One good thing about forced induction is that you do not need a radical cam at al to make great power. This means you can have like stock idle quality, great drivability, fuel economy, and still have a ton of power on demand.

I am not sure about CARB legal being you live in the socialist Kalifornia. But the car I mentioned had all emmisions equipment and passed the dyno emmisions test no problems.

I would asume they are looking for trouble codes, most of witch turn the check engine light on, (esp ones that efect emisions) so if your check engine light dose not light when driving than your probly safe

oh ok,i was under the impression that the test was to see if all the sensors were working properly (not desensitized and all that jazz) and reading what they should be at.
