440 Engine still in 1977 RV, not a standard Casting Number

[mithdraug]

I have a 440 engine still in a 1977 Dodge Dreamliner RV.  The Casting Number is 440-1-Eng, 4031645.  Code#OV1645.  I am interested in finding out more about this engine.

Picture of it would do wonders here.

Ok......... A picture is still worth a thousand words. Need to see if it's the "Industrial" 440 look-a-like 413, with the goofy heads, Cast crank or not, what actual numbers/symbols on engine ID pad, etc.
