2.8 to 3.4 swap

I am looking at swapping my 2.8 from my 85 s- 10 blazer which I drove into the garage and adjusted the timing and now cant get to run to a 94 camaro motor which is a 3.4.
will the motor and tranny both hook up (4x4)

yes your existing tranny will work fine with the new motor. You will have to use the camaro ECM and engine harness though.

Depending upon what year it is you might only have to swap the oil pump pickup tube, and the oil pan.

You'll probably also want to use your flex plate or flywheel. But it has to be balanced the same as the 3.4L
Later 2.8L motors were balanced the same. I don't remember what year they made the change.
