Nope, they haven't. I had a Dana but the car makes 1800trq and I haven't seen any fab Dana's on the market. They really don't have a 727 either that is proven to handle 2500 + hp. I'm bleed Mopar but you have to be realistic sometimes. At least I didn't take the cheaper route and put a big block Chevy in her. lol Regardless, my baby is alive and running and that is what matters...
