Its pretty damn cold here on LI, NY now and as usual i'm struggling with getting my 5.0 to heat up. I work close to home and the engine is just starting to warm up by the time I get there. I know this is not good for a bunch of reasons. I thought about using an electric heater over night. Either a block or oil pan heater. Anybody use them? Are there any good models for my car? How do they work? Thanks.
