Ironically , I just purchased the C-130J off Steam ,..checked to make sure it was indeed the new "authentic" soundpack (CS_C130.PC.PCK) and the soundpack that I hear is T-56 ..is an Allison..not the powerplant that drives the J models.. so im confused..you have not updated the E and H's with this because it didnt coincide with the J model..yet it has nothing to do with the J model ?. I lived on an airbase for 12yrs,..father flew the c-130H for 20yrs so am very very well learned in what 4x  T56 Allison bolted to a C-130H sounds like.
