    I am taking a 1989 S-10 Blazer and turning it in to a offroad truck. I am going to put a GM inline six in it with the stock drivetrain. What will I need to do to use the four wheel drive. It has a NP231 transfer case in it

    How much of the firewall and dash are you planning to cut out to make the inline 6 fit? /forums/images/graemlins/yikes.gif That's a pretty long engine!

    the entire body is coming off because it is so rusted so space is no issue

    well you are going to have to either have to extend the engine out the front where the radiator is , or you will have to lengthen the front shaft and shorten the rear shaft.
    i think the old inline six has the same bolt patten as the
    4.3 bellhousing but i could be wrong. if so , you will have to see if there is an adapter to hook the 231 up to the
    original tranny. if you pull the tranny from a k5 blazer
    with an inline 6 , you could see if a 231 can be clocked
    to have a driverside drop. good luck.

    A vacuum switch on top of the transfer case engages the central axle disconnect when the case is shifted into 4WD. /forums/images/graemlins/cool.gif You can also buy a manual control unit, called a Posi-lock, for around $100.
