    How tough would it be to swap in a '94 350 fuel injected motor where my '77 305 is???
    I "ass-ume" that it will bolt right up to my TH350.

    What would I need to take with the motor to operate the fuel injection?

    Can I take only the motor or does the computer need th tranny as well.

    I don't mind piping in the exhaust O2 sensors or anything but I just want someone to confirm I won't drop a crap load of money trying to get it to work.

    Thanks guys

    Yes the TH350 will bolt right up to the motor I have swapped my 700R4 out for a Built TH350. No these Engines ECM dont read anything from the tranny they are OB1 computers. If it was newer with the vortech and OB2 then yes you might have to do something bout the tranny. Just get all the harness's for the ECM and sensors off the truck. It shouldnt be too hard to do this swap b/c there isnt a lot of sensors and there all easy to replace. /forums/images/graemlins/thumb.gif
