Cummins piston wrist pin height

300ft is all I need
I've searched a lot and came up with nothing. Can some one help me out with wrist pin height (crown to pin centerline) on a 6.7 QSB piston and the less common 4.1" bore 6.7 that was used in Ag equipment?

Thanks in advance

Much appreciated! I couldn't find that info for the life of me, very helpful.

Thanks again,

Thanks smokem, I appreciate the help.

Is the 4.1" bore an actual cummins engine or is it the iveco/caseIH/ new holland counterpart?
 
It was produced by Cummins and used in a few different applications, I had a good bit of info on the piston some time ago, but I do not recall where it is now. Referencing the pin location, the same value represents both 4.21" versions, I believe the smaller bore had a different compression height.

Along with a 38mm pin. I can picture the post where you put the info, I know it's on here somewhere. I've had those pistons in my hands on several occasions, I probably wrote it down somewhere where I was sure I'd remember it......
