Re: Flathead Block Heater
This is new to me. I have had my hands on a few[hundred] Flatheads but none with this device{as far as I remember}. I guess this was not a popular option in my limited circle. I wonder how well this performed? It would seem a heater in the temp sender tapped holes might be more efficient? But, it is probable an additional 20 degrees, when ambient is zero, would be helpful.
