im in texas. you will have to use components from the year motor u install. 4 o2s, cats purge solenoid ,evaporation canister .i install the canister at the stock location on my truck and the bracket has a small bracke where i installed the new purge solenoid.
im also using longtube headers. i have just finish my swap fired it up friday only codes i have rigth now are p0101 and p0449 . 2nd is for purge solenoid which i think the canister is bad since im using the old one in the truck not the new one i bougth . p0101 is for something todo with mass airflow im taking it to a local tuner to get checked.
by using a swap motor you will be able to add bolt ons later on as you will only need to pass emissions for the motor /vehicle you took the motor off. by using the erod you wont be able atleast not in cali since that will void the carb certificate.
