I did learn physics. I was 14 when I had my first physics class, and had my doctorate degree at age 22.
Your block lose no heat by convection when you're not moving (if I understand physics well enough, your car isn't moving when you start it first thing in the morning). There is no difference between starting your car at -20 with zero wind or at -20 with 60km/h wind. Once the engine is firing on all cylinders and you start driving, it may even get hotter in the 60km/h wind scenario, assuming you're driving with a tailwind.
I just leave this for you to read :
