I went out this morning to follow my own instructions that worked around 30F but it had been as low as 5F this morning. Needless to say I had to double all of the cranking times and then repeat!
If you do a search on Detroit 453T you will find tons of info on the Web. Somewhere I found a Detroit service manual from the military.
The motor that Tucker used is an industrial fan to flywheel configuration that was not put in highway use vehicles. I believe all of these 453T configurations were built in Brazil and can be verified by a different serial number series than the highway engines.
Here is a link to a bus company that has a bunch of good Detroit info.

There is a guy on YouTube in Northern California that has some good video of him putting highly modified motor into an old GMC and another in a Diamond T.
