S&S 41/8" pistons are machined to such close tolerances that it is not necessary to measure the piston Additionally, the low friction coating on the piston skirt makes taking measurements very difficult Therefore, hone cylinders to nominal diameter 0 0005" for correct clearance vStock crankcases must be machined to accommodate the large spigot diameter of 35/8" bore cylinders
