I have an 86 ford with the 8.2/at545 with 6.5 rear gear
There is a group down at the bottom of the home page for Detroit/mechanical drive train.
My bus will only do 49 on flat roads,wide open and haven't tried any hills yet. I know I will make it to the top I just don't know how fast.
My bus came directly from the bus barn and the old timer's told me a few stories(not lies) about ones that there churches bought in the past and some followed the advice of the old timers and changed the gears and there's is still on the road and the ones that turned up the motor to get more are dead in the water.
I can't get them to reccomend what gear to change to because of liability.
I have heard change the whole rear and I have heard just change the gears. I like just changing the gears because I know what I have has been taken care of maitenance wise. Some reccomend gears in the 5.4 range and some recommend 4.3 but in my opinion gaining speed is losing towing power in the rear gear sizes but I am not an expert or pro in this choice by far and am still looking into the issue and don't know when I will have the time or money but 49 it is because the Jolly Roger is gonna go somewhere every year even if it is slow I have no problems pulling a loaded car on a trailer, like its not even there.
Please let me know where your info/decision takes you.
The military still uses the 8.2 two stroke in some of the baddest trucks in use (dragon wagon )
I don't know the tranny or rear end I will never afford them anyway. A lot of people hate the 8.2 and they said the true mechanics are a dying breed? Why is the military using boat anchors for engines.
