Your request for a lightweight yet durable crankshaft for the powerful big block Chevy engine has been answered. Callies’ design team has optimised material distribution throughout this crankshaft to produce a component that is strong yet easy to balance.
Many BBC crankshafts are counterweighted to offset simple balance forces detected at main bearings 1 and 5 by today’s precision balancers. Callies Magnum Mass Correct counterweights have beenstrategically placed to reduce imbalance forces over the entire length of the shaft. The result is a crankshaft that exhibits superior bearing life and minimal wear.
