That is a fairly desirable engine code. As a V code that would be a 440-6 pack car. It's also a BS which makes it a true 'Cuda (as opposed to a Barracuda or Grand Coupe)
I used the following site to do a quick decode.

END End of Codes
The bold codes I am not sure of. I know the code you have is LOS is the date code where the first digit is the month (1-9,A,B,C,D) the second is the year (0=1970) and the last indicates the day. My guess is 105
N4 is missing a digit. I'm sure some of the better code readers will be along
