    Do the Magnum XL and ultra billet big block chevy crankshafts need balancing? If they don’t what are the balancing specs, thanks Dave

    1. CalliesAnswerTeam says:


      The Magnum XL and Ultra Billet BB Chevy crankshafts do need balancing. We highly recommend an internal balancing job. If you need help coming up with your bob weight, feel free to call us at 419-435-2711 and ask for a tech.

      Thank you!

    What is Callies feeling on useing the small end of rod and special pistons to control lateral movement of rod on crank, so weight could be taken off sides of big of rod? This would be useing your ultra 5.7 rod in a SBC, flat top pistons, 10.8 CR, 585 HP, 485 TQ, 8500 RPM.

    I plan on building a 735 cid big block chevy using a Dart 31293865 block, and your magnum crank BB542B-MG. The block has a 10.6″ deck height. What length rod would be best? 6.8″ or 7″?
