Okay, so this is one of those duh moments. I really should not be trying to think too much that late at night....

Of course I have a 216. The casting number prefix is GBA so that means that it is a 216 cubic inch from 1949. I knew that already but suffered from a "senior moment." Now where did I put those car keys? :-)

Thanks
