ok like a 340-4bbl?

Have a 66 HEMI block and need help decoding. First of all I don't understand the coding so if we could start there and what the sequence means, that'll be a big help.. Here goes.. first digit N, second is either an M with the first leg missing on the left or a V with an extra leg to the right.

Anyway, here's how it looks...N, whatever letter, 42622390016.

Any help or education would be appreciated....Gary
