An Eagle 4340-forged crankshaft is heart of the engine's rotating assembly. By keeping the stroke to a short (for a big-block) 4.000 inches, the engine will sacrifice some low-end torque, but make up for it with higher horsepower and a greater rev range. Also, crank flex won't be a worry as the revs climb. With torque an inherent attribute of a big-block, the few extra lb-ft that would have come with a longer stroke won't be noticed on an engine we intend to use on the street as well as the strip.
