This means that with a 9.000 block height the longest rod that can be used with a 4-inch stroke is 6 inches. If you are building a 3.75 stroker then, a 6.125 Scat Premium 7/16 rod can be used with a piston having a 1-inch compression height.

Usually, the skirt friction experiences a rapid change during the break-in period largely due to the wear of the machine marks or roughness against soft coatings. It is thus important to consider the effect of the change of the roughness for a …
WebbThe piston effect can influence the movement of air, not only close to the lift shaft, but also in the wider area of the building or structure. These air movements will affect the ventilation flow paths throughout the structure and can induce undesirable air movement in relation to wind-driven fires, blowtorch effect, flashover, backdraught, or fire gas ignitions.
