If you're planning to build your 350z engine make sure to add Performance Crankshaft. The Performance Crankshaft will give your Z the extra power it needed for every day tuner. The performances crankshaft is the working arm of the engine. All the force generated by combustion and the downward motion of the pistons is focused on the crank throws. The Performance leverage effect of the force exerted on the crank journals twists the shaft and converts the up and down reciprocating motion of the pistons into rotational motion of the performance crankshaft. This creates torque that the crankshaft uses to turn the flywheel and rest of the drive train. The rotating mass of the performance crankshaft combined with that of the flywheel and harmonic balancer also creates inertia and momentum that keeps everything spinning. This gives the performance crankshaft enough energy to push the pistons up on the compression and exhaust strokes, and to pull air and fuel into the cylinders on the intake stroke. It is basic physics in motion and the torque that's produced is what propels every gasoline and diesel powered vehicle on the road today. For stock engine rebuilds, a reconditioned stock crankshaft should be more than adequate. Most passenger car and light truck cranks are cast iron and have enough strength to handle the loads produced by a stock or slightly modified engine. If the Performance OEM crank happens to be a forged steel crank, which are used in some high output engines as well supercharged, turbocharged and light diesel engines, so much the better, because forged steel is much stronger than and not as brittle as cast iron. But when an engine is being built to produce serious power or will be used for racing, a stock crank may not be up to the task. When the loads experienced by a crankshaft start to double or triple over that of a stock crank, all bets are off as far as durability is concerned. So get yourself a Performance Crankshaft for a better Performing Crankshaft.
