Brass resist corrosion better. Rubber freeze plugs I only use in an emergency until I can pull the engine and do it right. FEs use 49/64ths freeze plugs not the 48/64-3/4 plug they try and sell for them.

they do sell 49/64 at autozone but the brass is 18$. and once again O'reilly is useless (as usual) about giving a proper description of something so they have 19 different one's but you don't know what they are made of....

O'Reilly just bought Checker and Checker got their 49/64s from Dormans. My 360 had steel ones and boy did they all rust out at about the same time, 10 years too soon.

Be aware that most brass core plugs are brass plated not solid brass. Good ones are brass but brands like Pioneer are simply lying to us. Take a magnet and check them and you will find almost all of the off brand brass ones are really plated steel. Hawkrod
I always brush a bead of Avaition Permatex (brown gunk in brush-capped bottle) on the band of the brass freeze plug prior to installation. It aids in installation as a lube and seals imperfections in the freeze plug bores.
That is a great idea and us Ford Techs did it that way. Fords manual says use a oil resistant sealer for the cam plug but we got in the habit of using Permatex on every expansion plug.

Be careful I use brass plugs in marine engins because of salt water. But after 17 years I would say that 9 out of 10 blocks will bust before the plug pops!!
