car came with a 318 poly , 727 pushbutton going to a open rear 8 3/4. has the tapered axles. so what info do i need to determine to get a working suregrip in it? suggested gearing . i have a mild built 440 and a b/b 727(pushbutton) and drive shaft out of a 65 cornet that is rebuilt with a stage III transgo shift kit. primary use will be commuting as a hooligan to work (7 miles and 11 stop lights) and occasional highway. no strip . gas and tire economy not a concern...
