CHEV 454 DOME TOP PISTONS 4.290 BORE +10.5cc DOME 8.7:1

Description

These ruggedly durable
pistons are made with
exclusive high strength FM425
alloy, and enhanced with
16.5% silicon for excellent
tensile strength and scuff
resistance. This advanced
metallurgy permits tighter
bore clearances, which help
minimise noise on cold engine
start-up. These pistons are
the ideal choice for street
performance applications and
late-model replacement.

More Sealed Power
hypereutectics benefits:

• Higher
  strength than cast or forged
  at operating temperature
• Finely dispersed silicon
  particles provide a highly
  resistant wear surface and
  reduces scuffing
• Lower material growth allows
  pistons to be fit tighter,
  improving cylinder sealing
  for less blow-by and more
  power
• High silicon
  content allows elimination of
  groove inserts in certain
  applications
• Designed
  toretain standard ring gaps
  in the top groove
