The Manley Platinum Series forged piston set for Chevrolet small block has a 4.030-inch bore, 1.125-inch compression height and 11.00 cc crown volume, suited to higher-compression or specific chamber designs. Forged from domestic 2618 alloy and fitted with tool-steel wrist pins, these pistons use cam-and-barrel skirt profiles to balance power with cylinder-wall care. Exact ring lands, unique fixturing for groove squareness, and moly skirt coatings on select SKUs support long-term precision.
