Think we were talking about flat top pistons readily available from the market for a Rootes engine application. There is no doubt that forged and lighter pistons requiring heavy modifications could be a better match to full race requirements. For those, however desiring fast road reliable engines w/o big mods the JP flat tops could be interesting though. That's why we have investigated about them. By the way, even the Holbay +120 HP engines used cast flat tops. Will crosscheck your weight statement for 0.040" STD piston . Think they are definitely heavier - all in - than the JP's...
