block heaters for our cars?

Im curious but are there block heaters availabe for our cars like a coolant heater. At nights it can get pretty cold some nights here and ive already seen my first snowfall and my first few nights of hard and cold starts where the motor is just turning over but not igniting the fuel properly.

Perhaps a different, better option is to upgrade all of your battery cables to 2 gauge with real copper inside. Then upgrade the ignition to direct fire and do a rebuild on the carb. Then lastly rebuild the engine with nice tight clearances to the tighter side of factory spec. Also be sure you have a fast healthy starter. Your engine will be able to start in subfreezing temps. The engine will have more power than it does now, and the power will alway be there, even in the summer time on hot starts which are usually harder than when they're cold. No need for a clunky block heater.

But it seems water has gotten into my oil now

wouldn't it be cheaper to hire a guy, we'll call him woodhouse, to drain the fluids, take them inside, heat them up to the proper temperature, and then put them back in?

Rotaries, at least old-school ones (so, not RX8, Gen 3 RX7), HATE cold and are a biotch to get to run in winter weather. In Alaska (caveat: NOT my SA - she is put into hibernation), we use:
-battery blanket or underpad heater. Warm battery= plenty of strong cranks. $35
-oil pan heater: same idea, but glued/stuck to bottom of oil pan. Warm oil circulates quick, getting it up and in fast
-block heater: NA for old rotaries
-coolant heater: as said, ungainly things: ones I have seen will essentially splice into upper rad hose with a heat element (some used to wrap AROUND the hose).

Works on our Piston cars at -40F or worse....
