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.
