455ci Engine Build Part 1- The Devil's In The Details

Piston skirts and crowns were coated by Swain Technology. The thermal barrier on the top helps keep heat from the ring package and instead uses it to expand against the piston for potentially more power. In theory, it also helps quench detonation by increasing the flame speed. The skirts were coated with a dry film lubricant to reduce friction. Erney polished the piston tops with "0000" steel wool to improve the reflectivity of the coating. View Related Article
