    BB-Chevy Supercharged Pistons


    Manufacturer's Part Number:

    Speed-Pro developed powerforged pistons and set the pace in powerforged technology. The high silicon VMS-75 alloy is found exclusively in pistons "powerforged" by Speed-Pro. Up to 3,000 tons of force forges aluminum slugs into the basic piston form which creates a grain flow pattern in the structure providing excellent strength, ductility and improved heat dissipation.

    Please Note: All compression ratios are figured with a gasket thickness representative of those commonly used and are approximate.

    i notice the dish area would be on the top of engine on #s 1,3,5,7 and on 2,4,6,8 on the bottom of piston. The 454 heads have combustion area on bottom on both sides. Similar to a chrysler hemi is there 4 pistons for left side and 4 different pistons?

    Asked by: back to me
    These are sold in "engine" sets and will have the correct piston for both sides of the engine.
