I have recently completed a 4BT install in my F-250 CrewCab,it is connected to a '93 M5ODR2 5 speed and 3.55 geared axles with 32" tires and I am happy with the combo around
town and on the highway even pulling the trailer the trans ratios match the 4BT's power band perfectly but offroad and on the older/forest service roads I need lower gearing.
I am thinking about splurging for an Atlas 4 speed T-case with the 2.0/2.72/5.44 ratios but that is a LOT of money and I need advice/input from people that are a bit detached
from the project I fear that I might be a bit myopic at this point after over 3 years and more money than I care to think about.As I see it the Atlas would be ideal for my application
as the 2.0 low range is synchronized to allow shift on the go and it has a 2 low ability. My other option is a ZF5 for the lower 1st gear that would help some but I am limited to small block ford
transmissions unless I buy a different adapter and flywheel and the gas ZF's 2nd to 3rd and 3rd to 4th spacing's are a little wide for the 4BT. So if I go the diesel ZF route I will be out aprox.
$2,000 and have a lower 1st which would help but not be ideal. With the Atlas it will be closer to $3,500 but I will keep my ideal on road gearing and have MUCH better gearing off road and
in the mountains for both up and down hill. We chose to do the Cummins swap in this truck instead of buying a newer diesel truck so I would still be in for less cash then if we had bought a
newer rig and the simplicity of it and lack of regulation it is encumbered by are both pluses for the '68 not to mention the emotional attachment we have to it make keeping it our choice.
So does the Atlas sound like a reasonable choice? We plan to keep this truck for ever and it is what we will use to travel when we retire so we expect to put a lot of miles on it and
it will be passed on to our kids after that so it is a long term "investment".
What do you think?
Thanks, Steve.
