I guess I'm asking the electrical gurus - does the block heater draw too much power to run through an inverter (300W), and would that be able to run off a battery for say, 2-3 hours before charging again? If it is feasible (or has been done) I am very interested.

I understand one of the most power sucking things out there is to jam enough electricity into a metal rod to heat it up, what you're doing in essence is a controlled meltdown. I also understand converting DC to AC is quite inefficient. I was going to try something similar, a friend who knows DC talked me out of it.
Install new gp's, adjust the valves see if that helps.
