Manley Small Block Chevy LS Series 4.065n Bore - 1.304in CD - -10 cc Dish Platinum Series Pistons

Built from domestic 2618 alloy forgings, these Manley Platinum Series pistons are designed for Small Block Chevy LS engines with a 4.065-inch bore. The -10cc dish volume is a key specification for achieving a desired compression ratio, and the 1.304-inch compression distance is critical for valve clearance and piston-to-head relationship.

Manley uses proven cam and barrel skirt profiles that help manage piston rock, reducing wear on cylinder walls while still generating substantial power. The ring lands and grooves are machined to exacting standards, which is essential for a tight ring seal and maximizing combustion efficiency. These pistons also feature tool steel wrist pins for added durability, and the unique fixturing Manley employs allows for skirt turning and ring groove machining in a single operation, ensuring the ring grooves remain perfectly square to the piston skirt. This attention to detail is why professional engine builders and tuners trust Manley for high-performance applications.
