74 N code 400-4

There's a Charger for sale near me that's VIN indicates it came with an N code 205 HP 400 4 barrel.

I'm not familiar with this one, but have seen many P code 250 HP and M code 2 barrel motors.

Mymopar.com lists both N and P as having the same compression- 8.2:1

So what is the difference?

Mymopar also shows a California spec 440, but doesn't say anything about the N code, which is the first thing I thought of.

M code = E63 on tag
N code = E64 on tag
P code = E68 on tag

Interesting.

I thought all the 400 cams were the same by then.
