Does anyone here use an engine block heater on their Hemi??? I'm wondering because I'm tired of freezing to death going to school every morning and having the truck finally warm up as i pull into my parking spot. I did that last winter and don't want to do it again lol. Anyways I was wondering if having the engine block heater would help my truck warm up faster. I live in MA where the temperature will be 5 to 25 degrees every morninging. Thanks in advance.
