From what I can tell, my pistons are these http://cgi.ebay.com/ebaymotors/ws/e...d=1,1&item=8004816147&sspagename=STRK:MEWA:IT , clevite TC-1852 , or at least they have the same markings as mine http://www.chevelles.com/forums/attachment.php?attachmentid=1163



Clevite lists them as 8.5cr, but gives no more info that I can find.

Any help appreciated, thanks , Kevin

So I think these are 12.5cc "double quench" smog pistons? Can anyone confirm this?

Thanks, Kevin
