Flathead Block Heater
Given that this engine was living in a 1939 Coupe in Minnesota it is not surprising that probably during an engine rebuild a block heater was installed. Never have seen one in a flathead before but maybe not that uncommon in the Northern climes? Just a bit of carbon buildup on the pistons(LOL), smooth bores with a tiny ridge at top. No stamp on pistons with an oversize, haven't measured bore yet. Been in a corner of the garage for 4 plus years but ran when pulled! I did hear it run with a rigged up earlier distributor while it was still installed in car. Winter project time is here.

Re: Flathead Block Heater
My very first vehicle was a 1950 F-1 panel truck there was a block heater on the left side head it was actually really nice replacing the stock head bolt I never used it during the winter since living on the second floor made it impossible to plug it in. The heater is still installed in that engine which is stored waiting for the day I decide to freshen her up and use it once again.

Re: Flathead Block Heater
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.

Re: Flathead Block Heater
5851a, that is is a great link to the actual manufacturer of mine, thanks for that. Hoping it will be as easy to remove as it probably was installing back in the day. Light snow here today but not a very bad winter so far. Probably jinxed myself for posting that. Hoping for Spring now and not later.

Re: Flathead Block Heater
I had a MK 7 Jag when first married, in NZ, it had a block heater, it was a thing like an electric jug element that screwed into a large threaded hole in the side of the block, it had a standard 3 pin socket that connected to the 240V house supply.We lived out in the country and in the winter we used to plug it in over night, when you got in to start the water temp was already up.

Re: Flathead Block Heater
I’ve never seen a head bolt heater. But I never ran a Flathead in my younger days. I’ve seen dipstick heaters and I used a few that went in the lower rad hose.
I remember my father putting a light bulb on top of the motor and draping a blanket over the fenders to try to keep the motor warm. Tried anything to be able to get to work in the morning…..Mark

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.

Re: Flathead Block Heater
I was given one years ago, still in the box. It's somewhere in my stash. This one was designed to go into one of the head studs that hits water. The gentleman who gave it to me was an Eastern Airlines mechanic in Newark, NJ. They used them on the tug trucks since they were flathead powered. Winters use to get really cold in the NE and he said they were needed since a lot these tugs were left outside and it was a bear to get them started when they were ice cold with single digit temps.
Mine is like Ralph G's and has a male plug on top of a heating element that sat on top of the stud. |

Re: Flathead Block Heater
Not related to block heaters, but to the first pictures. The heads on that engine are 38 24 stud units typically only found on the 38 only 24 stud motor with smaller mains like the LB-37-38 21 stud engines. Can you post a picture of the crank pulley and front of the crankshaft, that will ID 38 or 39 engine type.
