Competition Pistons and Rods - Anyone have solid model files?

[GO 4LO]

Anyone have any solid model files or engineering drawings of Cummins pistons and rods? Prefer UG files, but should be able to convert whatever you've got. Thanks!

I have all the important dimensions . use then to make my new rods , and pistons , but the only dimensions we used off the Cummins was the rod width



The wrist pins is different , the length is different , and the rod journal is different

Do you mind posting the dimensions of the stocker? I wouldn't ask for you custom design - just like to get a baseline stock piston so I can build from there to design my own. Thanks.
