GM block heater
 

I have had this for decades. Time to go.
First $25 (+the ride) gets it.

Do you know what size this is? I'm interested in it for my early 454.

The metal part with the "O" ring is 1.445
The OD of the "O" ring is 1.64"
It has to fit a 1.5" soft plug.

Thank you for checking. I checked my freeze plug and it's 1.75" so it won't fit.

Great NOS part, good luck with the sale.

We used to use those to heat our water for coffee/tea back in the remote areas of the plant....
