Roller 360

Im considering picking up a 360 prolly from a van..im thinking maybe mid 90,s or late 80,s.a newer version with F/I OR CARB.it would be AFTER LA motor..would this block be a direct fit into my duster..are the motor mounts the same as the 360 LA motor.would a torque flite be the the same ..as always,all help appreciated..j
