i'm swapping a 4.3 chevy motor into my isuzu amigo soon and i'm trying to get info on the different trucks and options this motor came with. what trannys? what t-cases? when did they switch to CPI? When did they switch to OBD-II? also i may be pickin up a totalled S-series blazer and i was wondering what kind of interior options they came with in the mid 90s. power seats? are the seats comfy? thanks a lot guys.
