Looking for opinions. Anyone with proven methods? What's the best way to remove the rear driver side freeze plug on a SBC? I've only through experience removed one with a chisel and a slide hammer. Has anyone drilled a hole and screwed into one? What about using a punch on the edge to rotate the plug about, grab it with a channel lock or vice grip? I'm installing a block heater, and this time, I'd prefer not to have the plug come out after 2 hours of swearing and slide hammering.

In the car or out? Sounds like in the car. That sucks. I worked with a guy had the rear freeze plug on his 350 Pontiac Grand Prix rust out or come out on him. This is the one between the block and flywheel.

I think I did one once, punch and hammer to get it cockeyed and then grips to lock on and yank it out. So, you pretty much already had the idea. Took a lot to get it out. I leave them alone most of the time.

Make sure it is square in the hole. And only in as far as the other ones are, don't go too far.
