8 3/4 or dana

I'm thinking about a 500HP small block with a 4 Spd. My question is should I do a 8 3/4 or spend the extra $ for the Dana? This will be a street/strip car. It will see more street then strip but either way I drive my cars hard. I know a 8 3/4 is a pretty strong rear end but the Dana is a great rear end. Thanks for any input.
