Just picked up Internally Balance 360 Cast Crank today. The crank was balanced with SRP 360 .040 pistons. Scat I beams rods. Weights are shown on the worksheet. The crank still took one slug of Mallory in the front and rear counterweights. Attached is the worksheet I think, scanner at work does not want to work for me tonight so I took a picture of it. Will scan to pdf sometime tomorrow after MATS.
