Speed Pro Forged Coated Pistons for Pontiac 455 PLUS Moly Rings
P/N L2359NF-KIT
About Speed Pro street series power forged pistons:
These
Speed-Pro forged pistons are made from extruded VMS-75 aluminum alloy
that's forged under 3,000 tons of pressure to "near-net" shape. After
that, they're machined to their final configuration. These pistons
offer excellent strength and durability and are capable of taking the
punishment that's dished out on the street and in competition. They're
available for a wide variety of applications, including OE replacements
and all-out racing engines.
