You can't do it just letting the car idle, you need to drive it and put a load on it to heat up the block, oil and exhaust.

I had a 396 with a comp 280H cam, fairly aggressive. Never touched the car over the winter and never had a problem. Use a good oil, maybe throw a battery maintainer on it and cover it up. It'll be fine until spring. Even the battery will be fine with no maintainer if it's fully charged. No computers on these cars so nothing to drain the battery. A lead/acid battery will hold it's charge for months, like 5 -6 months, in cold weather. It takes more amps to start in cold weather but heat kills batteries, not cold and heat will cause it to lose it's charge a lot faster than cold.

Agree with you Hank, the worst thing you can do is start your car up so your buddies can hear is roar. If you not going to drive it don't start it up.
