Thanks Fats!
WillH, the rod beam is not perfectly aligned with the centerline of the big end bore :the narrow side of the big end bore goes toward the rear of the engine and the wide (heavy) side goes toward the front....when you look up at the underside of the piston on assembly (if everything is correct) the pinbore will be more or less centered under the piston to equalize the load....when we turned the pistons around on the v things only the piston was reversed; the rod was installed normally, that kept the load centered.....the six cylinder rod is basically the same dimensions as the small journal 283 rod with the exception of the big end width; you do not want unequal loads on one of these or they will make funny looking drain holes in the pan....fats
