Camaro ride in winter.What do I have to bear in mind?

Hi guys, I’m going to get a Camaro MFI 2,8l 6V BJ`86 this week.Unfortunately, I don’t know about US Cars at all.Can anyone give me a tip on what I have to take into consideration in winter? Are there any technical problems or driving behaviour? There are 215 M+S tyres on it, should I rather buy smaller ones? I’d be grateful for every tip.
