Hello, Just wondering what the best s10 power train would be for strength and durability, and or what are the weaknesses of certain years, I am looking at the 4.3 engine power train in particular, as in, what would be the ultimate transmission, transfer case and differentials and why, what are their designations and what years do they come in, please keep in mind I am looking for factory gm parts or modified gm parts, not aftermarket. Thanks
