8x4x2 is around 400 uk gals...that's 64 cubic feet.
I think smaller tanks stunt growth without a doubt although water quality, food and water changes also have large impact. Pheromones are know to build up and stunt growth in fish so a small tank with low water changes versus a big tank with lots of water changes will result in different sized fish. Keeping a young ray in a small tank will possibly hold it back. I think high nitrates also hold fish back but far less proven.

We will have to agree to disagree about the tank size thing 
I kept my male in a 72-18-27 for just under a year fed him twice a day and changed a ton of water. Within a year from front to back he was wider than the tank was. At 1.5 years old he is big for a male that is why I think the water quality/ changes will dictate growth.
Here he is next to a tape measure about a week ago the red square is the 12" mark
