Sites to learn how to work on cars?

I am a total newbie to cars...... i really want to learn how to work on them and what all that stuff means..... anybody know of any sites that could start me off? Another thing.... i have a 78 caprice with a 305 v8 (i think) but i was told it was a 350...... anyway the engine says 305 so i assume it is 305..... is there that much of a difference between a 350 and a 305?

-thanks
