71 Charger, Have a 340 and I'm updating to a Tremec 5 speed. Wanted to go with a Dana but was not sure of the best vendor?

I have a strange Dana 60 in my 68 with the tremec. I used 3.73 gears. With the 36% overdrive and 295/50/15s it's perfect. I had 275/60/15s on it and if I were to run those I would go with 3.90 gears for sure, as those are about 1.5" taller.p
