Biggest Rear tire setup on stock 68 dart 14" wheel

The 245 60r14s are starting to sound like the best bet. It winds up being about 25.5" tall and close to 10" wide. That seem correct and reasonable for fitting back there? Compared to the 185/50 r 13's that are there, discount tire's calculator makes it about 5" diameter larger than the wheel there already, so I'm guessing it'd be about 2.5" higher in the back than the front. I'm curious if that will visually rake the car at all, which is what I want.
