Crankshaft Balancing

[sscam69]

John why did Da. Ch go with a V-10 configuration as compared to a V8 configuration.?


I was reading that a V-10 config allows you to achieve "Big Block" cubes but generate less harmful emissions compared to a V-8 configuration given the same amout of cubes

The V-10 configuration allowed "big-block" cubes (for torque) with "small-block" combustion chambers; this reduces the surface-to-volume ratio in the chamber, which allows for more complete combustion (shorter flame-front travel and reduced dead-space volume above the top ring land) and simpler emission controls.

The pulleys just drive the belt-driven accessories (water pump, alternator, power steering, A/C compressor, etc.) - the crank drives the cam with toothed sprockets and a chain (the "timing chain") so their relationship never changes; the cam sprocket has twice as many teeth as the crank sprocket so the cam turns at 1/2-crank speed.

Okay, thanks, John! I understand now that the timing is calibrated with the cam modding and sorts. Thanks again!
