Block Heater Part Number?

[ARAMP1]

Well, I tried to install a GM block heater that I bought last year and it turns out that it is the wrong one. Just a bit too small.

Anyway, does anyone have a GM part number (or even a NAPA number) for a block heater that installs in a 1.75in. freeze plug hole? (it's for a 454)

I don't have a part number, but when I lived in Colorado I was able to get a block heater at the local Advanced Auto Parts store. They had a decent selection and could order one for just about any application.

I ended up going by the dealer today and ordering one. Hopefully it's the right one.

how do you go about removing a freeze plug? drill it out and then stick something in and pull real hard?? been thinking about installing one in my block, but i haven't had any trouble starting it below 30 just yet, and it doesn't get much colder than that here.

The task of removing the brass plug from the block is fairly simple. It gets complicated when there is something in the way (motor mount, starter, sensors, etc.) What I usually do is take a blunt object (all I seem to do with screwdrivers is poke holes) and hit the freeze plug on one side. Usually that breaks it free and it is easily removed.
