The Manley Performance Platinum Series forged piston set for Chevrolet small block engines with a 4.035-inch bore, 1.250-inch compression height and -4.00cc volume. It is intended for engine builds where lowered compression and forged strength are desired. Constructed from domestic 2618 alloy forgings, these pistons use cam-and-barrel skirt profiles and tool-steel wrist pins. Select SKUs include moly skirt coatings. Manley's fixturing and exacting ring lands enhance ring seal and machining repeatability.
