Define CA smog legal? Do you mean legal as technically or just the sniffer? LT will not pass legally, but if they do not do a visual and you have cats you will stand a better chance. Also, for this to happen it will be a pricey package, as you will need to purchase all of the supporting mods (ei: EWP, UD Pulley, FAST 90/90, etc ...). A manual will stand a better chance of reaching that number, versus an auto.

i'd say 400-450 "Might" be doable... but not 450+ and pass smog...

but a safe bet would be a 224/224 114 cam with a set of AFR 205's....

A bottle of nitrous would be a good means of making this happen. It can be removed for the smog test much more easily than LT's.

Another approach is to supercharge the engine. I assume this is an F-body, so you would have to go with one of the smog legal Vortech kits. Otherwise, Magna-chargers are smog legal for several other applications.

If funds, space, and time permitted, id leave the stock motor in to pass, pull it for a much nice motor everytime, thats only way to beat it. And HOPE when you do get pulled over and officer wants to check everyone of your CARB #'s that you dont have to get reinspected.

A lot of being able to pass the CA Smog test is:

1) being able to pass the visual (missing equipement, missing Cat's and/or LT are a problem)
and
2) a good tuner with a scope/infraRed to tune with.
