CHRYSLER 383 ROD 6.358 FLAT TOP +5CC 2V KB HYPER PISTON SET

MIA's Description

The United Engine & Machine Co KB162.030 is a set of eight hypereutectic pistons designed for BB Chrysler 383 engines. These pistons feature a flat top with two valve reliefs, a 4.280-inch bore size, and a 3.380-inch crankshaft stroke. They are constructed from a 390 aluminum alloy with 16 percent silicon, allowing for tighter piston-to-wall running clearance.

The KB162.030 pistons include CNC-machined pin bores and come with wrist pins and spiral lock rings. The piston rings themselves are not included with this set.
