Terry, I believe there should be a 3 in front of the numbers your listed.
According to the Mortec web site casting # 3731548 is a 1957. Those numbers
were used on 265's and 283's also they do not have side mounts. You can also
check the head casting #'s on their site too. http://www.mortec.com/
There is a chance it's a 265 so the head numbers should confirm which it is.
Either way, Great Score!
