360 balanceing

When I did my 360 I had KB psitons, much lighter than stock, and Eagle rods also lighter than stock. The machine shope balanced it and needed to remove approx. 200 grams from each end of the crank (almost a pound). When they balance your engine they will need the pistons and rods to figure the bob weight to put on the throws. You will get a better balance if you provide the harmonic balancer and flywheel or flex plate/torque convertor you plan to use verse them using standard weights.
