I’m working on my Big Bolt again (1953 350-24 with a GMC 302), and finally got the cooling system plumbed up and filled with water, only to realize that there are 3 of the freeze plugs that are rusted through and leaking!
The freeze plugs seem to measure 1.210” by measuring the block (with the plugs still installed as I don’t want to pull them without having replacements)… I can’t seem to find a freeze plug online anywhere that is 1.210”…. 1 see 1-1/8 and 1-1/4 everywhere, but none that are 1.210!
Help!
