What type of dart do I have?

I think there is consensus that this is a 1966 Dart with a 273 V8 but we need either the fender tag or the build sheet to determine if it was a 2 or 4 barrel carb (and we all know the the 4 barrel has higher compression and crinkle painted valve covers etc…)
It has the larger capacity brake master cylinder reservoir that was only on ‘66 A-bodies with disc brakes so that is most likely original.
The distributor has been changed with some other alterations. The windshield washer reservoir is missing along with the pump.
