OLDSMOBILE 455 ROD 6.735 STEP DISH +30CC KB HYPER PISTON SET

MIA's Description

The Keith Black KB132-060 is a set of 8 hypereutectic pistons designed for Oldsmobile 455 engines. These pistons feature a dish top, a bore size of 4.186 inches, and a crankshaft stroke of 4.250 inches.

Constructed from a low-expansion 390 alloy with 16 percent silicon, these pistons allow for a tighter piston-to-wall running clearance, making them suitable for high-performance marine, drag race, circle track, street, or towing applications. They include fully machined head and valve reliefs, triple spiral lock rings, CNC-machined pin bores, and diamond-finished skirts.
