I drove my 5.0 Stang through 2 Edmonton Winters. There are a couple things that you can do to help out.
1. Get
GOOD snow tires. Don't cheap out on this! Good snow tires are key.
2. Increase the weight in the back end. I used 4 50lb sand bags. You'll need the wieght to help with the power.
3. Drive intelligently. With good snow tires you can actually steer better than some other cars. That 5.0 wights a lot and help with traction in the front end. You have to be real carefull with the torque in the rear. Pick your routes carefully and there are days when you should avoid driving.
Always have patience when you drive, it will save you.
Use your head and you'll have little or no problems.
