John,

Great images of the shield! You-da-man! https://www.yenko.net/ubbthreads/imag...ns/worship.gif

What car & build date did this shield come off of?
Galvanized steel- huh? So much for the stainless steel
only issue? I wonder why some were stainless and yours
is not. Production use vs. replacement item perhaps? https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Anybody care to chime in on that?
Steve

This is a swap meet treasure. The guy I got it from had no idea https://www.yenko.net/ubbthreads/imag...lins/dunno.gif what it came off of. He was just cleaning up his garage. I was glad to help him out.

John - buddy !!! https://www.yenko.net/ubbthreads/imag...mlins/cool.gif

Would you like to be a nice guy and "help me out"?

Re: 69 big block starter heat shield
 

Is the shield stainless or galvanized?

Its a no-brainer!! Galvanized steel is magnetic, stainless is NOT. Use a simple magnet if in doubt.

Keep in mind that GM always used two different part suppliers to avoid interuption at the final assembly plants. Its possible that some cars got stainless and others got gavanixed.

Some kinds of stainless steel are magnetic, others are not. My heat shield certainly seems to be stainless, it is nice and shiny and has no rust or pitting. But it attracts a magnet too.

Yes some stainless is magnetic, it depends on the nickle content. I believe 304 stainless is non-magnetic.
