My question still remains in regards to balancing the entire assembly with what will likely be light weight pistons and crank with heavy factory rods... $$$???...
Maybe? With an external balance setup, the counterweights seem to be plenty big enough to allow for balancing. Mine did, and it uses OEM rods. No Mallory, and a balance is $200 in my town. Might be a different story if shooting for an internal balance.
