327 in a '74?

In a previous post I asked what engine I should put in my 74 nova. Currently it has a I-6, and thats too weak. Someone told me to put in a 327, how much would it cost to buy a 327? Where can I get one?

A 350 would be cheaper and would make more power... a 327 is only cool because it's different! I had one in my 74' Nova (65 327), and I yanked it for a 69 350!
