ROSS big block Chevy pistons listed here are designed for forced induction applications, such as supercharged and turbocharged engines. They have thicker ring lands, larger pin bosses and increased internal radii to withstand the additional cylinder pressure that forced induction engines put out. These forged piston sets are ideal BBC pistons for street and marine applications, as well as drag racing. BBC pistons use pins that are .990 diameter and are 2.930 inches in length. All piston pins included are aircraft quality chrome moly and are retained by double spirolox, or they can be press fit into rods. When using these big block Chevrolet blower pistons in extremely high horsepower applications optional ROSS tapered bore pins part # 990-04-29, are recommended. Lower compression ratio is achieved by utilizing more deck clearance than normal (flat top below deck, larger deck clearance than for a normally aspirated engine). The Ross piston sets listed here can be used in turbo engines and can also be used with nitrous oxide NOS injection. These sets are available for stock 454 blocks and stock stroke cranks, as well as large 4.500 bore based blocks and also stroker cranks. See the table below for exact specs for each part number.
