Re: [AMC-list] Aluminum 195.6 Freeze Plugs

[Joe Fulton <piper_pa20@xxxxxxxxxxx>]

Yes, I know they are not actually freeze plugs but that's the common term.  I apologize for triggering the sermon on the mount but this is an educational forum too, so I'll stand corrected.

Actually on the intruction sheet in the kit, the the plug is referred to as a core plug.  But in researching the name Welch plug I came across the name of the spring manufacturing company which first patented this type of plug in the early twentieth century.  

Dave Stohler, it appears that they still make plugs in the correct large diameter for this 195.6 motor (excuse my engine).  

I'll measure the plug and give you a part number by tomorrow.

Joe Fulton
