010,020 casting marks?
Some blocks have a "010" above a "020" under the timing chain cover, I understand that to make the block more desirable over one without these casting marks, is that true? If so, Why?
I was told it represented 1%zinc and 2%nickle added to the block during the casting process.
Thanks,
LOST
Some blocks meaning Chevy small blocks.
Thanks
