Winter Storage in a non heated garage attached to the house

[C4UC101969]

I am planning on storing my truck through out the winter months in a garage that is attached to my house so it is fairly warm in it in the winter maybe gets down to 30F to 20F at its lowest points, but I do plan on taking it out once in awhile if weather permitting as they are promising snowy and really cold winter this year for us. Is there anything in particular that I should do to it so that there are no problems with it through these cold winter months......I wish I lived down south but unfortunately we here in the north have to deal with white and cold mother nature for next 6 to 7 months at least, unfortunate fact of mother nature. My truck is a stock 69 307 with 4 barrel carb, any suggestions for inside storage and occasional use.
