GM block heater

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

Re: GM block heater

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

Re: GM block heater

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.

Re: GM block heater

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