Too cold to start car

1) Choke or spend the cash and go fuel injection.
2) engine block heater the kind that goes in the coolant freeze plug- you drain the coolant, knock out a freeze plug, and install a 120 vac little block heater in the open hole per directions and refill coolant and plug in to outlet for at least 2 hours before starting.
3) for colder temps change the oil to 10w30 or 10w40


SN: did you check to even SEE if you had spark? Cold weather and weak ignitions do not like to play together.
I realize I am jumping on this train a bit late, but its lunchtime on a Monday... what else could I do?
