Big Block A body possible with a Column shift Automatic?

My 67 Dart is a pristine car with original paint and about everything else. 2 dr hardtop, bench seat and an underpowered 273-2. Up to this point I haven't disturbed really anything on the car yet except for different wheels and tires. It has a 2.71 rear with 225-70-15 rear tires. I drive my cars on the Interstate a lot. I was just basically thinking aloud with the big block question. Probably won't happen in my life time
My question is why do you want to keep the column shift? is it because that's existing and saves money? I've always felt fumbly trying to be a ricky racer with a column shift.
