I am researching major powertrain upgrades to a 1998 Dodge BE2500 4x4 orig. equipped with a Cummins 6BTA5.9-180, TorqueFlite 518 (Calibration 47RE), New Process 241HD and dual Spicer axles. As alternatives to the Aisin-Seiki 68RC refit that appears the best choice on complexity, I'm investigating the Allison 1000 and the Spicer ESO66-7. From the off-roader perspective, the theoretical best tranny is also most likely the trickiest--the Eaton-Fuller FRO12210B 5+5-speed, which can have up to two auxiliary PTO's straight to the rear (where exhaust heat can't cook things). What bellhousing and transfer case would I need to retrofit along with the FRO in order to hook up to the stock Cummins (which currently uses a block plate compatible with the Viper V10, yet)? And would I have to replace the block plate during the flywheel/clutch retrofit?
