I had a brain fart when I wrote that the metal was poured in there and stand humbly corrected! Armand is 100% correct... ------------- Date: Sat, 13 Mar 2010 13:47:51 -0600 From: "Armand Eshleman" <aje1@xxxxxxxxxxxxxxx> Frank said "They plug the holes used to pour molten steel or aluminum into the mold for the block (or head). " I said As long as we are being really anal about "freeze" plugs, and because it was mentioned we like to learn things on this list, and because it was mentioned about getting a lecture or something like that, I guess I better add my coins to the discussion. Actually the "holes" that the plugs fill are NOT where the molten metal is poured into the mold. The holes filled with "freeze/welch/core" plugs (I've heard them referred to as soffit plugs too) is actually the hole that the sand is removed from. The molds that cast iron blocks are poured with is made of casting sand. There I said it and I'm done. -- Frank SwygertPublisher, "American Motors Cars" Magazine (AMC)
