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.

Great price, but don't stack multiple wires
Size: 300A
I used this as a junction point on a 1 gauge wire. I added an 8 gauge wire to one side, and the cover would not seat. I had to bend and maneuver the ring terminals to make the cover catch. For the price of the items, if used without any secondary wires attached and interior use only, this is an unbeatable deal.
