Please help ID these pistons

Hello all.
Are these factory 440 hp pistons?
Don't see any markings on the top.
Haven't pulled the pan yet.

They are in my 1968 HP 440.



Thanks guys.

They look like OEM cast 440 pistons. In '68-69, 440s only used one type of piston, regardless of whether it was the 350HP passenger car engine or the 375HP performance engine.

they're some kind of trw/sealed power/etc forgings.

L2266s maybe... forgot the cast OEM pistons didn't have that hole in the center of the crown.

Thanks guys!

Unfortunately for me, they are .080 in the hole and I have 906 heads.

Sounnds about right for a stock-replacement piston in an undecked block.
