Thanks for the info, it was a car built in the USA, then it was imported to Peru several years ago, so according to the serial number it originally came with a 4bbl, at some point they changed it for 2bbl i guess.
The date code thing is correct, my bad on Matching # thing.
So far is a:
273 - 4 Barrel.
4 speed.
Kelsey front disc brakes.
8.75 Crown.
Hurst trigger shifter.
Bucket seats.
So i guess it's a dart with all the good extras!
Do you know what the original carburetor was? I would like to change it.
