A crankshaft contains two or more centrally-located coaxial cylindrical ("main") journals and one or more offset cylindrical crankpin or ("conrod") journals. The two-plane V8 crankshaft pictured in Figure 1 has five main journals and four conrod journals, each spaced 90° from its neigbors. Figure 1: Example (2-plane) Crankshaft

This is no small matter as most crank manufacturers consider the design and machining of a proper fillet radius one of the most important features of a racing crankshaft. In particular they have begun to favor a non-circular contour or non-constant radius that is thought to impart greater strength to the transition from journal to throw.

A forged crankshaft made of 5140 grade steel alloy is a good upgrade and has around 115,000 psi tensile strength. A 5140 alloy contains less carbon (0.38 to 0.43 percent) than 1053 alloy (0.47 to 0.55 percent), plus it has chrome (0.9 to 1.7 percent) and silicon (0.2 to 0.35 percent) to improve durability.

Many cast cranks are made of 1053 high-carbon alloy steel. This material has a tensile strength of around 100,000 to 110,000 psi, which is good enough for applications up to about 400 to 450 horsepower (depending on the size of the journals). But for higher horsepower street or racing engines, some type of forged or billet crank is a must.
