These small block Chevy 350/400 inverted dome top pistons by SRP are made from 4032 low-expansion, high-silicon aluminum alloy that's heat-treated to SRP specifications. The ring land and crown thickness have been specifically engineered for mild turbo, supercharged, and nitrous applications. Their forced pin oiler provides increased wrist pin lubrication. A pin fitting, double Spiro locks, and a wall wrist pin are included. The CNC-machined ring grooves accept 1/16, 1/16, 3/16 rings, which are sold separately.

Some parts are not legal for sale or use in California on any pollution-controlled motor vehicles
