Well, I have to say again that the 727 was in the car when the previous owner bought it. The Duster had a 318 from the factory with I guess a 904 trans. Sometime later a 360 with the 727 trans was installed in the car. The whole deal was trying to get better gas mileage which is nothing I care about. I bought the car cause I'm very good friends with the previous owner. The car looked good and I know the car was done right. I could hoop in it now and drive to Virgina and back and not worry about anything. I love MOPAR's and would love to have it all mopar but this is one thing I have to over look.
