Flathead Block Heater

[RalphG]

Yes, head bolt heaters were pretty much standard equipment up here in cold country on any engine you planned to start in winter. Dad had one on the 52 Merc. When my brother overhauled the engine in 1980 he did not re-install the head bolt heater as we had no plans of running it in winter. I've got several of the old head bolt heaters saved here. Not sure if any of them work.
