The JE Pistons eight-piston kit for Big Block Ford M-6049-SCJ applications supplies forged pistons sized to a 4.440 in bore with a -39.0 cc correction. Forged and machined to match across all eight cylinders, the pistons incorporate JE’s FSR forging design and accumulator groove to reduce friction and improve ring seal for consistent combustion behavior in BBF engine builds.
