Car shuts off when put in drive

i would check your float level. i had the same issues, same carb, 360/904. my carb was loading up and flooding the secondaries because a float was sticking.the motion of the car going into gear was rocking the float and fooding it out.i rebuilt the carb several times even using floats out of another one. take the top of the carb off and see how high the fuel is in the bowls, if they are equally level and where your floats are .this may or may not be the problem, but it was mine. then take it off and apart and clean clean clean it. i have since put a holley 600 on it. best move ive made in a while.
