The Manley Platinum Series forged piston set for Chevrolet small block specifies a 4.035-inch bore, 1.250-inch compression height and -4.00 cc crown volume, suitable for modified or stroked combinations. Made from domestic 2618 alloy forgings with tool-steel wrist pins and cam-and-barrel skirt profiles, these pistons deliver precise ring lands and groove tolerances. Manley's unique fixturing yields consistent groove-to-skirt squareness and select part numbers include moly skirt coatings to reduce friction.
