Hey there I got a fairly mild 454 (cam, slight head work, intake, headers, .030 flattops 10:1 and 150hp spray) going into my malibu with a powerglide transmission. Just wondering if there was a decent priced diff that would work in the car I am upgrading to a strange 9 inch when the money is there just would like to track something down so I can have it together for summer and not worrying about blowing up the stock diff that is in it now any pointers would be appreciated thanks.
