FERROTHERM A steel piston top and an aluminum piston skirt that are flexibly connected via the gudgeon pin. These matching horsepower and torque figures would mirror changes taking place with the Vortec 4200 for the 2004 model year. Piston diameter, installation clearance, and if applicable direction of installation are marked on the piston crown. The stated piston diameter added to the corresponding clearance gives the cylinder diameter. Engine oil flowed into the phaser and operated a helical spline and piston. Due to the manufacturing process, they are stronger and therefore allow reduced wall cross-sections and lower piston weight. Pro LS 2618 Forged Pistons. Each time they are removed unnecessarily and refitted with excessive stretching, permanent deformation is caused and the operating performance is impaired. Pooling fuel will seep past piston rings and contaminate the engine oil, so this was a huge advantage. Critical rod dimensions are are held to very precise tolerances of +/- .0001 of an inch, which is the tightest tolerance you will find in the performance and racing aftermarket.
