Aluminum piston (unknown) 12v

[Jacob-s]

Hey guys so I came across a set of piston at an estate sale and which to me and my untrained eye looked to be early 12v billet pistons is what I assume if someone can actually tell what they are that'd be great but any who I purchased them in hopes of someone could use em and I could pass on the saving or maybe use as cool paper weights with that being said I'd like to ask
25 each+shipping. I have 8 total I will try to load pics of not I can text them
Pm me for my number

Should be a part number on the piston

Edit* never mind, overlooked the "billet" part.

Lil too big for a 5.9 ain't they? Isn't a 5.9 4" bore?

I don't have my caliber on me to check
Been off work for 6 months now otherwise I would of checked
I was just hoping it'd be obvious to spot but I honestly have no idea I'm no engine expert with hard parts.

Anyone know what a 6.7 is off hand??

What are the pin bore dimensions? (Diameter and clip to clip)

4.21"... the bowl looks like a 12 valve though.

More pics sorry I don't have a caliber at home

1.5470" is pin diameter on a stock wrist pin

Thanks for all the referencing for me

This looks like it may be the real deal. Just wish they had steel ring lands.

In the first pic you can see the interior of one piston. They're not billet.

Just an observation but those have massive rings. Way bigger then a Cummins. Looks like it has 1/4" ring groove

Stock wrist pin measures 3.250" long

x2 either cast or forged and then machined.

Here's a few more pics
I've been curious for months about these just kinda forgot I had them

 

[Jacob-s]

I don't wanna label them as something there so thanks to all for the input

Based on the shape, cast.
