On a 1933 Ford v8 original engine Piston rods are labled 1L, 1R, 2L, 2R... Puting these in the right place seems obvious except is there a particular orinetation of the labels. Ford example should the stampled "labled" piston rods be placed with the label toward the oil pan rail? Does it matter if the lable points toward the front of the motor or rear?
