Callies Magnum Plus Crankshaft
The next standard in high performance crankshafts. They feature shaped and profiled counterweights for enhanced windage reduction. Of course as all Callies cranks they use high purity 4340 alloy forging, close tolerance machining, and heat-treat. All throws have Angalite lightening holes and pin arms profiled. Small block cranks also feature gun drilled mains for additional weight savings. Typical big block weighs 68-74 pounds. Requires chamfered bearings.
