I found a 78 Z28 tonight , it is supposed to have a 373 possi. I jacked the car up ( no tag on the housing ) turned the right wheel 3 full rotations and the drive shaft turned 3 and 3/4 rotations. I know there is a way to tell the gear ratio this way but cant remember how. ANYONE know? Also while turning the right wheel foward the left wheel turned backwards but not if you held the left wheel. possi or not? Thank for any help on this.
