Description

The KB Hyper Performance Piston Kit (KB155KTM.020) by Keith Black/UEM Pistons is a set of hypereutectic pistons designed for high-performance Chevrolet Small Block V8 Gen I 327 cubic inch engines from 1962-1969. Crafted from a low-expansion 390 alloy with 16% silicon, these pistons allow for tighter piston-to-wall running clearances. They feature fully machined heads and valve reliefs, CNC machined pin bores, diamond-finished skirts, and mini grooves to reduce scuffing. Wrist pins and spiral locks are included, while piston rings (1/16 x 1/16 x 3/16) are not. This kit is for a .020" oversized bore.
