Unknown

Hello Group,

 

Could we repeat the information on casting numbers for the Super Six engine block indentification.Al Saffrahn is starting a rebuild  for what he belives is a 1925 or 1926.I am suggesting to Al that he sign up with our group to get more information as he goes along.

 

Thanks in advance!
