Taking advantage of coating technology, the pistons for this build were sent to the experts at Swain Technology for thermal barrier coating of the crown, and an anti-friction coating to the skirts. Hemi engines have considerable piston surface area which presents a challenge to thermal inefficiency. The thermal barrier helps retain combustion heat with the goal of adding power through greater efficiency. By the same token, stroker engines will present greater thrust loading and rod angles than short-stroke engines. Friction-coated skirts help put the slip to friction at the source.
