    Yeah, externally the motors will be pretty close to identical. There will be some minor differences in the timing cover for a vented opti on the 95+ motor, and you'd need to change over all the appropriate 96 sensors and accessories onto the 94 motor.

    Yeah you're only going to run into minor differences here and there on the earlier motor. Shouldnt be anything too costly to convert though.

    This. Definitely want to stick with OBD I, if you have a choice.

    Not sure how you can say that considering the tunability of the LS engine family vehicles, which are all OBD2.

    What does that have to do with wanting to switch from OBD2 to OBD1? I'm not even sure why someone would want to. There are tuning options for OBD2 LT1 cars.

    i'm saying that tuning an ODB2 LT1 car is getting hard and there are no free options. ODB1 LT1 car has free options and ODB1 is more forgiving when you change things... i have read that you can !egr and !air and not set off SES lights on ODB1.

    Who is talking about the LS1 engine.
    When it comes to LT1 tuning, its a lot easier doing it with an OBD1 computer.

    So what? Tuning a PCM is best left to an expert anyway if you want the best results. And OBD2 offers more options and ways to make a better overall tune.

    I for one like SD better than the OBDII setups for the simple fact that is easier to deal with and has less electronic requirements.
