Highway rear end gears on city bus??
I need to get some more speed out of my 87 Flx Metro. I am considering changing out the rear end. I will post the gear ratio tomorrow after I find out what it is. There is a 3 speed allison trans, I beleve it is a V731 and the rear end is geared for city driving. I have heard that highway gears are hard to find for this V drive bus, however turning up the engine and adjusting the govner or putting larger tires on the back, sound like half a** solutions as they will eat more fuel and put extra strain on the already under powered engine. I just want to be able to do 50-55 up hill, but I am no speed daemon.
My questions to you all are...
Has anyone ever done this with there bus, flx metro or other similar bus, and if so what gear and pinion did you use, and how did it work when it was all said and done?
Also, where is the best place to find new gears and pinion?
Will doing this affect fuel mileage and hill climbing ability positivly or negitivly?
And, are there other options that would help other than changing the gear and pinion?
I am getting about 60-65 MPH flat ground, but I am really loosing speed on hills. I have a new engine going in the bus right now and a newer transmission, so i am thinking that that may get me some more power on the hills.
