Big Block Chevy Pistons
BBC Pistons For use with Blowers and Turbochargers and Open or Closed Chamber Heads
ROSS big block Chevy pistons listed in this section were designed for blown and turbocharged engines, and have thicker ring lands, more massive pin bosses and larger internal radii to withstand the additional cylinder pressure that forced induction engines put out. Ideal bbc pistons for street and marine applications, as well as drag racing. BBC pistons use pins that are .990 diameter, 2.930
length, .150 wall and weigh 149 grams. All pins supplied are aircraft quality are are retained by double spirolox, or can be press fitted into rods. When using these bbc pistons in extremely high horsepower applications, ROSS tapered bore pins part # 990-04-29, are recommended. Lower compression ratio is achieved by utilizing more deck clearance than normal (flat top "down in the hole").
* in the note field means that these bbc pistons include
oil ring support rails.
