Lifter ID ?

Hey Folks,

Anyone happen to know what brand this lifter might be? Motor was built by a prior owner, and there's no documentation. So, I'm trying to figure out a bit more about it.

72 340, KB higher CR 1970 replacement pistons, unknown cam grind, but seems to have a fair amount of overlap. Forged crank.

Thanks in advance for any info you may be able to provide.

Be well,.
