With all due respect, welders can do amazing things nowadays. Check Jerry M's sight
and you will see pics of the original block from my Zl-1 that had the snowflake ground off and 'put back on' by melting a piston and making a plug w the snowflake using another original block to make a mold. Than a hole was made using a holesaw and the plug welded back in... After a reskinning of the whole block the repair is unoticable.

I did pull out an original xram and a new offy unit that i had for years and took a look. I am 99.99% sure this base in question is not a GM base..nor a repro.. ( I also have a repo unit I bought a while back) ..

I am 99.5% sure it is an Offy base .. When compared w the pics of the base in question, the similarities are obvious compared to a GM unit.. Im traveling to brazil tomorrow, but i'll try to post a few pics...

Also the repo units are actually very detailed and excellent copies that are almost undistinguishable to an original..

Still wanna bet?? Just kidding !!
