You could create a system similar to the "cabin post-heating" available on MB euro models.... just have a block/engine heater (either diesel fired or electric) , and an electric pump (strong one) plumbed into the cooling system, and have it circulate hot water through the system, it'd keep the engine warm, and if you got real fancy and creative and attached a trigger for the blower to run at a low speed + monovalve to open, then you'd have both a warm car and engine.
As for me, I am a rugged michigander, I go out in the dead cold/snow, and crank-er up....preferably with block heater involvement coming soon, I haven't used it yet, but I think I will start to use it in the next few days, its getting cold!!! They said snow is in the foreseeable future...yeesh. Oh well.
