Yes I had considered the need for a balance - but wouldn't I have to do that anyway with the lighter SCAT or Eagle brand rods? The OEM 340 rods are on the heavy side. The classified ads on this forum is a good idea. But I need to get this engine done sooner rather than later and also with the shipping cost plus the cost of getting them redone (crack tested, resized, honed and new bolts) they will be more costly than a new set, even though I would prefer OEM rods in it.
