I just finished installing a 440 in my belvedere with a 727 auto trans. the motor and trans has been setting for about 8m,when I finished the install and put trans fluid in it.it only stays in a forward gear regardless were I have the shifter set.I looked under the car and the shifter is moving the trans shifter arm like it should any ideas?????

Did you fill the torque converter with tranny fluid before installing it? Is there a clear path through the tranny cooler for fluid flow? (This won't prevent operation) Is there any fluid flow through the cooler lines? This tells you that the pump is working.
