It looks like I will be heading to California toward the end of this year. I have been planning to rebuild my IROC for street use, but now I am wondering about restrictions in California.

Does anybody know the dos and don'ts for modifying cars in California?

I am guessing that there are heavy restrictions from the intake manifold back to the tail pipe.

The car:
1989 IROC
L98 350cid (305 originally)
T5 Transmission
Holley Stealth Ram Intake
Hooker Super Comp Headers - full length
and other typical ESP modifications to the suspension and brakes

thanks for any advice-

An LSx swap will require a trip to a referee, who will check that all smog equipment for the year of the engine is in place. Basic CA rule is smog equipment must be correct for engine or chassis, whichever is newer. They will be particular on the details, like the proper y-pipe and number of cats specified for the LS engine you install. Also, if you use any 50 state legal aftermarket parts, don't lose the CARB EO stickers that come with them. I have a couple buddies with completely legal setups, but they can't smog them because they didn't keep the stickers and the manufacturers won't provide them after purchase. And smog techs are paranoid because of random checks that will lose them their license.

There are a couple counties up here in Norcal that don't require the inspection, but no such luck in the LA area.
