4.10. I prefer clutch type sure grips, but cone will do. 489 or 742 case. 3.91, 4.30 or 4.56 will do in a pinch, depending on how much cam and converter you have, and if you are going to spend much time at highway speeds, but the first two options are kinda rare, and the last one is kinda low geared. I ran for years with 4.56 in my 440, 509 purple shafted Challengers with 3500 stall, however, including highway trips.

education on the suregrip as it applies to 1964 dodge 440
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...
