270 Dart Charger

If that's the fender tag off your car the engine code is 31, isn't that for 273 2 barrel Vehicles?

My 66 barracuda formula S was 32 for 273 4 barrel.

Maybe it's the wrong tag or ?

If I remember correctly the engine code was different between '65 and '66 for the 273 four barrel (or it was between '66 and '67).
