    i would think you would just take out all the electronic computer stuff and take what then would be a long block and put an intake and carb on it
    1. take unhook all electronics and trash it unless u want to resale
    2. take the intake and throttle body off along with fuel injectors and fuel rail
    3. buy a intake and carb that is California emissions legal and wala u then have a carbed engine also u might need to replace the dist. but im not sure with the fuel injected stuff.

    Thats what i'd do but then again i dont follow Emissions Laws either that craps a way for the Government to line their wallets.

    Not hard at all, I just done this for a friend on a 91 Dodge pickup, First you need to get a good fuel pressure regulator, EFI run's off [throttle body type] 18 psi, injector type run's off 45 psi, remove intake and throttle body, install new intake and carb, run line from regulator to carb set fuel pressure to 7 psi, fire engine and start driving, throttle cable same from one to other.
    Head's up the true drag race!!
