Decoding engine
 

Hi,
My son recently came into possession of an old chrysler engine.
We're not sure just what it is. This is the info we've been able to
get off of it:
Model HT413
Type-358-GA
Serial number E119949
Can anyone help to decode this and give us an idea of what we have?
I believe it to be a 413 C.I.
Thanks,
Jerry
