Description

ICON Pistons & Rings — Pontiac 428/433 (6.800" rod)

4.165" Bore (+.040") · 4.000" Stroke · -4.5cc Flat Top · Set of 8 with Rings

ICON pistons are forged 2618-equivalent premium alloy from United Engine & Machine, the same shop that builds Keith Black. They are the value-forged answer for a Pontiac that has outgrown a cast or hypereutectic piston — a healthy hydraulic roller street engine, a bracket car, or any build where detonation and heat are a real possibility.

What You Get

  • Eight ICON forged pistons
  • Matched 1/16, 1/16, 3/16 ring set
  • Wrist pins and locks as supplied by the manufacturer

Before you order: measure your finished bore before buying an oversize. Confirm chamber volume and deck height against your target compression ratio — crown volume alone does not set compression. Opened or installed pistons are not returnable.
