I've had rods balanced, shot peened, and reconditioned with new rod bolts for mopar small & big blocks in the past. They have the balance pads needed to make them a matched set. I admitted my idea was probably unworkable, because of the potential for damage to a given rod. It was just a passing thought. Since you can apparently balance them by smoothing out flash and so on that makes more sense. Elwood, are you able to get replacement rod bolts for these motors ? Eventually I see myself building one of them,and am curious about that. Too bad the 218/230 rods don't have balance pads like their bigger brothers. If a rod could be welded on to add weight, I would have been sorely tempted to do so while I was chasing tenths of a gram trying to balance these 230 rods. There comes a point when one is afraid to remove any more material. If you're asking about NOS rod bolts and nuts (and lock washers, if you're using the earlier style rods) for the small block flathead, then yes, they are still available, at least for the moment. As to the rod bolt availability for the big block flatheads, I don't know. Has anyone tried a replacement source such as ARP? I don't see flathead rod bolts in their online catalog, but maybe the right person there could provide some guidance. I really wish that the small block flathead rods had balance pads top and bottom. I'm somewhat envious of those big block flathead rods; sure would make balancing a much simpler task. Edited May 6, 2017 by Elwood Quote Link to comment Share on other sites More sharing options...
