Even at part throttle a 1-2 gear change doesn't bring the rpms down at all. Instead, it feels like being rearended by a Grayhound bus! The 727 has a 9-1/2" 3,500 stall converter that is pretty calm at cruising speed. I think I could use an even lower gear, maybie as low as 3.0.

Call DoctorDiff, he knows everything. I have the same issue with my car. I have a 512 inch engine and a 5 speed Doug Nash. I need something around 3.0 rear gear. I haven't decided if I'm going to change the transmission, or swap in a 9 inch. Last edited by AndyF; 05/02/12 07:06 PM.

Another option that may be doable with some creativity would be a Dana 61 3.07 gear into a 60 housing. I don't have any idea what the issues would be but it might be worth looking into. Even if these gears are no longer available from Dana they should be easier to find than a Dana 60 3.30 gear.

IIRC the 3.08 gearset requires its own carrier so try to get everything rather than just the ring & pinion...

Not quite the same as the standard Dana 60s I would like to find one of the Dana 60-1 out of a mid 1970 Ford 3/4 ton truck with the 360 V8 and the four speed truck trannys with the 3.30 gears in it, I would have it cut down for my Duster OP, how about using a lot taller tire on the rear to slow the cruise RPM down I did Mr.Cab Racing and winning with Mopars since 1964.

They're pretty hard to find. careful! those are a special offset pinion case diff. huge pinion caused the offset,will not fit in a standard case. ck info on any "under 3.54" gearsets....the pinion may not fit!!! mike
