I've had/have both 5 and 6 speeds. While I think they both have their benefits they also both have quirks I don't like but for what the owner of that car is looking to do Scott, the Tremec 5 speed will do everything he is looking for.
On our own personal vehicles I've run different Tremecs with .63 overdrive using 3.27 rear gears as well as 3.73's. The .64 version with 3.55's and several other swaps all with the 2.87/ .64 combo ranging from 3.50 to 4.10 gears.
He'll probably be really happy leaving the 3.23's and going this direction.
Generally with 3.73's and no overdrive, with a 27" tire I'm doing 60 at 2800. So he must have an extremely short tire to be turning that kind of rpm to do 60 with 3.23's.
