I Need Smog HELP!!!

[SRT Handz]

Well i bought a beater car to driver around since i dont like driving my stang in the rain and to school. Its a 1981 BMW 528i with 250,000 Miles on it. I took it to the Smog Place and it failed. To Many "Hydrocarbons". So i ask you guys, sinec mustangs owners are the kings of getting around smog stuff, how do i get it to pass. I am gonna get a new Cat but what else besides these....

Spark Plugs
Cap and Rotor
Timming
Cat

Is that good or what else?

my old hyndai failed smog this year and i had to replace the cat and have the intake manifold cleaned and it passed thru alright. i think there is stuff at car supply shops though that you can add to the tank to make it pass smog, i forgot the name of it though. sorry

was it just HC? what were the other numbers. it could be either running too lean or too rich. high HCs with high O2 is a lean misfire/lean condition. High HCs and high CO is rich misfire/rich condition. all of the above sound good. also running something like SeaFoam through will help.
