Keep hearing about frame twist with 440s

yes , it will twist the car . I did it with a 273 , 4 speed . Is it that you don't want to install sub-frame connectors ? Why ? Too expensive ? $40.00 is too expensive ? I was told by a chassis builder that frame connectors don't do anything . Haha ! this same chassis builder told me a 6pt roll bar won't stiffen a chassis . Haha ! Next time your door won't open after a blast , let me know .
