Maybe, or Summit? Federal Mogul has the Sealed Power and Speed Pro brands. Don't know who makes them or the Summit ones. Maybe United Engine and Machine if they're made in US, If china, who knows? Most of the brands of pistons, lifters, camshafts etc. aren't made by the people who's name's on the box. They're usually made by one company who puts the sellers logo on the box and sometimes on the part. Or that company gets them made by whatever company in china will do it for the least cost.
