While traveling the Alaska Highway in December, 1960, I warmed the engine of my old Chevrolet Pickup with a blowtorch and a 3' length of stovepipe with an elbow pointed before up under the pan before attempting to start it after an overnight stop in Yukon. The temp was 45 degrees below zero.
The truck started like Summer time, but the lubricants in the rest of the vehicle had congealed; the first quarter mile was like nothing I had previously experienced.
