    Pistons

    Hey guys ..

    What goes into determining what type of piston to get? I have a 305 motor that will be bored .040 over, 5.7 rods and will have a custom ground cam. The specs call for Aluminum pistons (Cast or Forged) Flat top max but dished/dome are allowed and they must have 3 rings above the pin.

    thanks for your help...
