Street Clevelands do not need a steel billet crank, which is purely a race piece for extreme-duty use. The crankshaft is important in any car because it is one of the major moving components that allows the pistons to fire in sequence as they were designed to do. Callies Crankshafts are at the top of the industry for quality of finish and reliability. As they always move two pistons together, the secondary vibration is twice as strong (and half as frequent) as cross-plane, unless balance shafts are used, with a counter rotating pair flanking .
