Hi, I have a set of 3.55 gears I'm running on my 67 R/T and was thinking of going to 4.10's. I just bought a new set of taller drag radials in anticipation of switching gears but haven't tried them yet. They run quiet and the posi unit is a little different than my other spare clutch type unit that has 5.13 gears for 1/8 mile racing. It looks like it has 4 pinions evenly spaced around it. Do you know brand it is? I'm kind of hesitant about getting rid of it because it works well and launches straight. The other thing is it's a 742 case. I had a 489 case before but don't really know what the difference between them is.
