20 + years ago I had a Ford Turbine engine that Eagle tested in 3 of the 05 Eagles,I still have a little info on it but nothing on a MCI with the Allision, Ford tested their turbine engine in trucks and I think Peterbuilt and GMC gave the Alllison a test in their trucks you may find something on truck forum. The turbine came and went away in a short period of time for transportation, I thought MCI tested the turbines before 1980 in the MCI 7 ?
Any ways the gas turbines didn't work out they used as much gasoline on idle as they did running full bore
