Crankshaft Being balanced on Sunnen DCB750

This is a Scat 4.00 Stroke 408 SBF Crankshaft being balanced on our Sunnen computer controlled DCB-750 balancer. This crankshaft had previously had the counterweights cut down in our lathe to allow for fewer holes to be drilled in the balancing process. Our balancer uses precision quick weights to simulate the rotating assemblies bobweight (Piston, rings, rod and bearing weights.) Pictured with a Powerbond SFI blanacer and Fidanza aluminum flywheel.
