freeze plugs brass or steel?

[bbeckwith]

Guys, I was wondering if I should use one steel freezeplug in my fresh 340. I have all brass plugs in the block, and got to thinking about using a steel plug in one of the heads as a sacrificial rust piece to help protect the rest of the cooling system. Am I just wasting my time? I heard about attaching some kind of metal strip to the radiator cap somewhere some years ago, but havent heard anyone talk about this. Can anyone shed some light on this subject?

Use the brass, the strip is an anode, it's to stopp corrosion of aluminum radiators.

Another thing on alum radiators is to use a ground strap to cut down on electralysis, silly as it seems, as well as a sacrificial anode.

hey good info jelsr, i'll have to do that to my dads '93 chevy truck. man, we were shocked when we pulled the radiator on that thing, it's a 2core aluminum radiator!

i never wanna replace the front bumper, left fender, radiator support, inner fender, and hood on a truck that hit a yukon again... i've no patience for body work...

always go with the bronze. they won't rust thru like the others.
