Speed Pro Hypereutectic Coated Skirt Pistons+Moly Rings for Chevy 400P/N H400CP-KIT
About Speed Pro street series hypereutectic pistons:
If
you're looking for pistons with an unbeatable combination of
performance and value, then Speed-Pro hypereutectic pistons are for you.
These pistons are manufactured from FM244 aluminum alloy, which
contains 16 percent silicon for greater strength and wear resistance.
They're also molded in the latest permanent-mold technology to ensure
the precise fit and tight bore clearances that today's top engine
builders demand. They're ideal for use in high performance street,
bracket racing, and oval track racing and will work perfectly with
normal ring end gaps.
